Admittedly, I drafted less than an optimal number of PAs and IPs, but fatigue in this league has been brutal. 15 ganes in, and I have only 3 players at 100%, These are all players I have used before, and I have not seen fatigue like this before. Have I missed an update? Has anyone else experienced this? Any thoughts, opinions, ideas?

I'm pretty much playing themes anymore and drafted according to my traditional measures.  That being said,  I'm suffering greater fatigue than I'm used to as you indicate.    Am still trying to determine why.  I have no idea if there were any adjustments to fatigue; I didn't read of any and I hope it's not the case.   At the end of the day,  I find myself batting pitchers 1st in the line up to help "calm things down" and it works to a certain degree. Wish I could offer more but this sympathy. rwc

More offense perhaps leading to more PAs used? Just a thought.

As far as I know there has been no change to the fatigue model.  Certainly nothing has been announced.

I think the most likely explanation is you didn't draft nearly enough PA.  You have a bunch of 500-600 PA players who have high OBP.  High OBP means all your players accumulate lots of PA.  Hence fatigue.

Hargrove, with 626 PA, the most on your team, has 71 PA in 16 games, a pace for about 720PA overall.  720/626 = 1.15, so he should be currently showing 95 fatigue.

Roberts (601 PA) is on pace for 715.  715/601=1.19, so he should be currently showing about 91 fatigue.

Huggins (535 PA) is on pace for about 620 PA.  620/535 = 1.16, so he should be currently showing about 94 fatigue, etc.

1450 is almost exactly what I would buy (edited based on crimsonblue's subsequent post - apologies for the confusion) for a 90M no AAA league. 

For an 80M OL, I typically buy 1250 IP, depending on park.  With the 10% bonus, that should give me about 1375 SIM innings at 100% fatigue, plus the 100 or so I figure I get from AAA gives me 1475 total available IP.  At a 90M league, without the AAA buffer, I would buy many more than 1250IP.

As for the hitters, all I looked at was pfattkatt's team, and I observe that based on the actual number of PA his guys are accumulating, they should all be fatigued.  In other words, the fatigue formula looks like it is working fine.

Thanks contrarian, but let me see if I understand you correctly.  I think you are saying that you would USE 1450, so  therefore the number you'd draft would be approx 1319.  1319 + 10% = 1450(.9).  and under normal circumstances this would be sufficient.  I think that's what your saying, so maybe my 1368 is just experiencing a short term fluctuation and will probably level out under average conditions.

No, I'm saying I would BUY 1450 in that situation. 

I'm in that league as well and totally missed the boat on how many PAs and IP to buy.  I have 5100 PAs.  At what percentage does a player generally start to underperform?  I guess I will find out soon enough and am taking this league as a hard lesson on the chin, but am curious on your thoughts. Thanks for starting this thread pfattkat and thanks for the insights contrarian.

anthother question is how many plate appearances does a player need to play every game with out going under 98% fatigue.  I know this may differ because some players rack up more plate appearances than others but what is a general estimate?

I think it is something 710  RL PA for leadoff.   Subtract 15 for every spot down in the order....or something like that.

I agree with most of the criticism, but I am just caught by surprise by this level of fatigue. I have used all of these players before, and hadn't gotten whacked like this before. Live and learn. It was obvious from the beginning that I was going to have to do some manipulation, I just didn't anticipate it being this bad. I hope that as the season wears on, things will "normalize" a bit.

From my experience, the ONLY time I run into the this type of fatigue is in theme leagues, never in OLs.  I don't know why, but it definitely seems that way.
