I gotta admit, I never had problems with waffle. Really low reject rates too.
I also admit that I am testing out clevermining to see if their claims of profitability match their stats. My reject rate there though....

Please report back, as this is a great piece of info. We can obviously claim 10% higher stats, if 10% of everyones hashrate gets rejected

I'm personally too involved to give any sort of non-biased stats, and I appreciate anyone that can come back and say "from time A to B, I earned C on wafflepool, and D on ". WP has things to learn from other pools, they have things to learn from us
Ran for 24h at clevermining, hashing at 3.6 MH/s, their website reports I had a 13% reject rate (0.5 MH) and my profits were 0.03139240 btc.
If you do the math vs my actual hashrate, that would only be 0.00872 btc/MH.
If you calculate it out vs my accepted MH, that would be 0.0101265 btc/MH.
So read it however you want. Your btc/MH is fairly accurate there based on accepted MH, not your actual hash rate.
Only 13%?? You got LUCKY ^_^ as for me I'll stick to my less than 1% on WafflePool haha
