Yeah, it sure is a black art. You must have been running a high compresion ratio ?
I used to have a problem with pinking on an A+ turbo engine I built. I was using 10.5:1 compression to negate some of the turbo lag from running a Garrett T3. Worked great untill I blew the piston to into a million bits. It would have been fine if I'd left it running 0.5 bar but I couldn't resist playing with the boost pressure. Damn cabit mounted bleed valves !!
