Some are claiming to do 40 windows in 30 minutes..yeah, right
There may be a couple that can trad that fast, personally I don't know of any.
I'll warrant that JM's times are pretty brisk for the work shown, and as that is WFP it is unlikely in the extreme that anyone could match it done trad, those are not small accounts, and the bigger the account, the bigger the time difference between the two methods.
Most of us think we are pretty quick with a squeegee, and I daresay we are...but methinks a teensy bit of exaggeration is being bandied about here :
And of course when you offer to 'race' the situation changes again, you don't work at 'race' speed, if some one is there with a stopwatch, and you are all primed and ready to 'GO!!' It really isn't going to have much relation to how you work from day to day
I like to watch others when they don't know they are being watched....and no, that doesn't mean Mrs B----- from No 15 when she takes a shower!!
