I can't explain this math (cutline)

Post by Deadheadz » Mon Apr 24, 2017 1:41 pm

Cutline gave me too many points for a player back in period 2.

I just caught this as I started only last night entering the results into a spreadsheet after someone posted that the totals were wrong from not having Saturday and Sunday this week.

Back in period 2 my pitcher Gio Gonzalez had 6 IP, gave up 7 H & 2 BB with 7 K.
The stats are correct and MLB game logs confirm.

I get 16 points but NFBC gave me 17 on the period 2 Team Stats. When you hover your mouse over the number 17 it even shows the stats that they used to get to that total.

How do you get 17 from those stats?

There was a scoring correction for this game at some point. Initially was scored an HBP for Justin Bour (vs. Gio Gonzalez) that was later changed to a walk which would change the total points from 17 to 16 points. Apparently the points aren't automatically recalculated when scoring corrections are made? It appears to be automatically corrected for roto-leagues.

Thanks for the explanation. I would never have caught that.
Just wanted to be open about even a small discrepancy. If I somehow won a prize I want to win it fairly.

After looking into it further, cutline is definitely not being updated for scoring corrections. Another example in Period 3, Russell Martin is being credited 2 points for the week when he should be -3. His 9th inning steal on 4/14 was changed to defensive indifference.

Well, I'm having a hard time figuring this out.

On Tuesday morning (5/2) I received an email saying I had 2650pts. At 8:31pm, I had 84pts for the day, yet my total was showing as 2722 instead of 2734. All the stats "appeared" to be updated. At 8:36pm, I had 101pts, the total showed me as having 2737 instead of 2751.

I don't know, I'm not about to start trying to calculate all these stats...when all is said and done, I can only hope the scoring is correct.

EDIT: At around midnight, I had 207pts, total showed as 2837, should have been 2857...assuming these stats are calculating correctly. That's a 20pt differential, either something was messed up early on, or it's not being calculated correctly. Email this morning showed me at 2837. I'll continue to monitor and see what happens.

Here is the what I think is the deal with that.

The cutline live scoring isn't optimized properly. Aside from Monday, everyday your live scoring +/- points will likely not match your actual +/- for the day, HOWEVER your actual total overall score is correct in live scoring any given day. Example given:

Say you have two catchers both scoring 2 points on Monday filling your two catcher slots. On Tuesday, your 3rd catcher (who had 0 points on Monday) has a good day and scores 15 points replacing one of your other catchers for net gain of 13 points (15 - 2 = 13). But the live scoring actually gives you a +/- of 15 points even though it CORRECTLY calculates the total score.

In this example if you had 100 points going into Tuesday, and the above hypothetical event is the only thing that occurred so far on Tuesday, your live scoring standings would read 113 Overall points but the "Change" would read incorrectly at +15.
Your "Today points" would also read incorrectly at 15 points. I think the "Period points" are correct but I am not sure.

I am pretty sure this is what is going on but not 100% positive. So a few more eyes on it to double check would be beneficial.

The scoring changes errors are still very concerning in my opinion. It seems some are included are some are not. Might have something to do with the day scoring change applies(4/6 and 4/14)? Here is the MLB's list of scoring changes: http://m.mlb.com/promo/scoring-changes

Four Examples of Scoring Changes that haven't been fixed in Total Points:

Period 2 - 4/6 MIA at WAS, Justin Bour reaches on a walk, instead of a hit by pitch by Gio Gonzalez.
Starters_______Pos__Points__IP___H__W__K__BB__SV__ER
Gonzalez, Gio__P____17____6.0__7___0__7___2___0___0

Period 2 - 4/6 DET at CHA, Error on third baseman Nicholas Castellanos in the top of the 4th inning, instead of a single for Tim Anderson. This also makes all four runs charged to Anibal Sanchez that inning unearned instead of earned.
Bench________Pos__Points__AB__R__H__HR__RBI__SB
Anderson, Tim__B____9_____22__2__4___0____1___1

Period 3 - 4/14 BAL at TOR, Russell Martin advances to 2nd base on defensive indifference in the bottom of the 9th inning, instead of a stolen base.
Starters________Pos__Points__AB__R__H__HR__RBI__SB
Martin, Russell___C_____2____17__1__3___0____0___0

Period 3 - 4/14 DET at CLE, Miguel Cabrera reaches on an error by center fielder Austin Jackson in the top of the 7th inning, instead of a single.
Starters________Pos__Points__AB__R__H__HR__RBI__SB
Cabrera, Miguel_1B_____36___24__4__6___2____6___0

The statlines are copied from the league I am in over the period in question. If you do the math, none of the points match up with actual line. The line has been corrected but the POINTS have not. These might not be all the errors to date as I have not checked all of MLB's list.

Since it’s optimal lineups, we are closing off the scoring changes at week's end. if we go back previous periods to update scoring, so much can change that would make it tough to determine the correct score. A player’s position eligibility can change, which would obviously affect the optimal scoring for multiple positions. Re-running scoring for every period to catch stat corrections would constantly change (potentially) the optimal lineups, so we finalize that week's scores after Sunday's games are done.

This is how it's been scored for the Cutline only the last two years. Hope this helps.

I did notice this morning if I go to Scores -> Live Scoring - Stat Line -> League Standings, these standing show different results than if I just go to Standings -> League. I believe the email blast that goes out uses the later, this perhaps is was messed me up earlier.

I do know that I'm already pretty much done with my Roto Leagues, seems impossible to come back once you are way down a month in...thank goodness for the Cut Line, once you make it in, it's pretty awesome! :)

Makes sense, thanks for the clarification.

There's no reason NFBC can't correct scoring changes in the Cutline for pitchers who aren't subject to the effect of position eligibility changes.
What will you do if someone misses out on the top overall prize by 1 point but can demonstrate that the "actual" scoring means he should have won? Sounds like a problem waiting to happen.

Will you crown me champion if I finish first by 1 point yet Gio Gonzalez scored fewer points than it shows on my roster?

Greg has already addressed this, scoring changes after a certain cutoff time are not part of the cutline game. It's the same for everyone, so it is not a problem.

We have a deadline for scoring changes in football (Thursday at 6 pm ET) and we finalize the grand prizes by Thursday of that following week. You have to have deadlines for these changes. With an optimal scoring league, we finalize the changes after Sunday's games. The week is final, as KJ said, for everyone. Everyone has this same deadline.
