BTW how is the uray deadline limiting handled cause from my brief look over at the github it looks like you cant submit things that are lower than your lowest deadline submitted, which while fair from a pool manager perspective the vast majority of other miners are submitting lots of low deadlines that aren't necessarily all lower than their current lowest but regardless of this it positively affects their score. Point being that you should either just slowly scale the threshold or simply use the algo provided by the site to calculate if the share should be uploaded

deadline value from miner is converted into share value using this equation
share = 1000 / ( NetDiff * Deadline + 1 ) 0.75
where NetDiff (network difficulty) is calculated by Block0-BaseTarget / Block#N-BaseTarget

note : to prevent user spamming low share, we implement share penalty of -0.001 on each submission for miners who submit nonce that has higher deadline than their (current round) own best deadline, as spamming low share is no use since pool will always pick one best deadline for every submitted nonce per round.

IE if your value isn't greater than 0.001 it definetly shouldnt be uploaded but something more reasonable would be to simply assume the -0.001 is in effect and not allow shares that would be worth less than 0.01 safely preventing scores from being lowered and slowly increasing the necessary deadline as needed Wink

on urays pool according to Uray, who i pm'd on something similar, only your best share is actually used. the penalty is to stop people trying exactly what you suggest, just to try and preserve system resources on the pool.

So if you first submit a deadline of 1000000, that's what you will get credit for initially, however if you then submit 10000 you will instead get credit for that one and so on... its not cumulative. If then after the 10000 you submitted 10001 you would get a penalty for this. So if you have multiple miners you will get some penalties as the miners don't know about the other shares the other miners have submitted, but it would be minimal, and you would just get credit for the best share submitted across all of your miners that use the same address.
