Anyone come across something like this before?

Lets sway you had a 70% SR and a POT of 1% over the past 1000 bets. Is there a way to get a idea of what the average draw down, and also the maximum expected draw down would be?

You could run monte carlo simulations against it and get a good idea.

Best to do this in MSExcel:
