I don't keep exact records but I think I relube with TF2 every 50ish miles....... ............. nothing collects muck like excess lube.
I don't spray TF2 on the chain anywhere near as regularly as that,probably every 200 to 300 miles,unless I've been out on an all day rain ride or prolonged rain storm,it definitely does get washed off in those sort of conditions.
I always apply,sparingly,(gently with the aerosol button almost trickling it on),after a ride not just before as it dries and soaks in.
I can usually tell when the chain needs a lube as it 'talks' to me
