I think it's exactly why. It's a reality check.

I had an ex who was a regional BJJ champ but really only trained with other girls.

I don't compete at all, suck technically, but I was able to demolish her in spars unless she pulled off a stroke. Even when she got a hold I could power through them in a way here usual opponents jest couldn't

She hated it but admitted it was a net positive experience because it taught her jest hire different we were built
