25% is not that good. 10% is normal and anything more than 20% should be addressed, especially in a performance car. The biggest thing, like compression, is that you dont want a huge difference between cylinders.
My old s10 had 80% leakage in one cylinder, but I really didnt give a shit cause it still ran great.
Just curious, was it leaking through the rings? Did you check to see where the air was escaping from? I would assume it was rings cause the whole dipstick ordeal but it could be other things.
