i can think of several occasions at autocrosses where i was sliding my miata around and would still place in at least top 5.

and i accept a challenge of skills at an auto-x event. you make a lap in your car. i make a lap in your car. then you make a lap in mine and you make a lap in mine. that ways theres no unfair advantage to knowqing your car. we can avergae out the times and see who is the better overall driver. sounds fun!
