It really depends on the car and other factors. It also matters how hard your car stresses the brake system, which in our E92 M3's is a whole lot. I could go many track days without bleeding in my E36 racecar, but that's partially because it was so light and had such effective ducting that it didn't really overheat fluid even when it was older fluid.

Decent fluid (ATE or similar) is cheap enough and bleeding the system is easy enough to bleed at least before each 2 day event for me.

I never liked the power bleeder, I have one and I still use the old fashioned 2 person method. My brakes felt consistently less hard when I used the power bleeder so I quit using it.
