I'm at 38K miles with many, many track events and the last analysis showed elevated lead at 6ppm. Keeping an eye on it but not concerned yet.

I have the Blackstone sampling kit in my apartment... I just never remember to bring it with me when I change my oil.

I do have an oil change I need to do before it gets really cold up here in Boston and the car goes into semi-hibernation mode. I'll get a sample then and see what my lead numbers look like.

(The car is in the shop for another issue; possible leak on cylinder 6 or funky injector. Fun!)
