I get tapped by white belts even when my technique is good. I don't care about "winning", and I never go 100% (it's usually between maybe 65 and 90). I'm just there to learn and improve and have a good time while getting a good workout, and consequently some white belts think they've really done something when they tap a blue belt, so they go really hard against me and I just kinda let 'em. I'm much more focused on improving my technique as opposed to ego-boosting. As a result of all that, I'm never avoided by anyone.
