As you say finding a good processor is a hit or miss and I agree, but you want to still improve your odds of finding that great OC'g processor and I am using VID as a criteria, others like yourself may choose the 'wafer number' (which I do not understand and never heard of until it was mentioned here) and the Batch#.
I think the only way to find out the Vid is to pop it in a mobo, I don't think they are batch or week related, it's a nice collection you made there but I think it's too theoretical mate, it will not guarantee it's the better clocker... many of the low Vids scale well ( volt/mhz ) but some are really weird and just don't behave as the previous one... and I had numerous E63/64/66/6850 and Q6600 already, it's really mostly hit and miss...

But I can understand you have to make a quick judgement when you buy ya CPU at the shop, I only watch A or B a( as my shop never has a wide collection available. Till now I prefer A over B as they run mostly with lesser volts (do'nt shoot me if I inverse it) at the same clock speed though B's used to run cooler... but those were in the E66 days, maybe stuff has changed with the SLACR's...

I'll have a look into ya great work you already did for us... will take some notes but like you claimed not all overclocks are based on the same criteria : user, hardware used, ....
