Hi Byron, 

I've been using shadow a bit-- I think these simulators are important for= testing, but Shadow, at least, certainly seems to have limitations, in some= crucial respects.  Running shadow w Tor (which is only logical, becaus= e many BCT transactions transpire over Tor) is not as 'light' as presented a= nd slows my own box down quite a bit, so the stats can't possibly be accurat= e... I don't know if this answers any questions or if you've had this experi= ence at all -- perhaps it is negligible on a more powerful machine than my o= wn-- or perhaps there is an adjustment still unaccounted?

Regards,
Nina K
