I think that you'll find the figure varies quite a bit?
I ran a thread quite recently questioning the speed on my egg, i'm currently running a Y board egg and it wasn't feeding above 12bps, nowhere near the "mythical" 19bps suggested in the adverts, and yes my egg is in as new condition and anyone that was following my other thread "yes i've switched batteries and only visually it makes no difference, havn't had a chance to put paint through it yet"
So Joey i don't think you'll get an exact answer.
I'm waiting for my Z board to arrive and i hope that will get me reliably above the 15bps limit as that's all anyone needs really !
I hope so anyway as i like my egg and really don't want to "have" to buy a halo !
