i also could not be embarrassed  by strong girls , becaus i like it . 
but once we play with boxing machine (dragon punch or something like that) and one girl did more than me ...not strong girl nothing special about her , but she did more . the second time again i did less , but didnt wait agin to her turn ' i just run to other fun machines there. 
i guess its not really measure anything ' and probably not calibrate anyway
