   I know the paper said that muscle mass estimates for past computer 
simulations may have been 45% lower than they should have been, but are there 
any revised estimates for top speed yet? If I remember correctly, past 
estimates ranged from 15 to 25 mph. So does this new information mean speeds in 
excess of 30 mph are much more likely?
