Is it currently possible to add any sort of profit weighting to pools to account for fees, or is that already done, and if not can I suggest it.

I will use scrypt and a couple of pools to explain what I mean.

litecoinpool.org : this is a pps pool that pays 102% : Profit value 102
ahashpool.com : current fees are 1% : Profit Value 99
zpool : current fees 1.25% + 5% : Profit Value 93.75
Nicehash : current fees 3-4% : Profit Value 96.5

This would allow the profit switcher to take into account the actual returns before deciding if/when to switch

So for example litecoinpool is paying 0.002050 and I have it set to only change on a 5% difference, the current profit switcher may see zpool at 0.002173 which is 6% more, but the reality is that's a losing pool switch.

TIA
