BB/100 calculation question in straddled game

I currently play exclusively on Club WPT Gold. They have the 200bb stacks but a mandatory straddle. I understand that makes everyone have an 100bb effective stack.

What's your opinion? Should I calculate win rate in BB/100 or in straddles as we are always playing in a straddled environment?

A lot of poker players like to lie to themselves and I would hate to be overinflating my effective win rate.
