Finding out your % of profit paid in commission

there's a log in site for people affected by the new PC regime

https://terms.betfair.com/

but it won't let you in if you're not. other than that - good question. I'd like to know myself.

The pc portal tells you on a weekly basis

But it annoys me you can't get an accurate current figure.

problem is that tells you commission generated, not paid.

aiui, once you're into the new charging regime actual commission paid becomes relevant.
