As part of this spreadsheet, I do a deep valuation of the cards I track and I often account for the overall SGC-PSA population (both separate and combined). I color-code each item -- blue is within 10% high or low of my estimate, green is 10%+ lower than my estimate, and red is 10%+ higher than my estimate. In general, I am pretty good at estimating the final price (hammer + BP) on items I am interested in.
I did this for the REA auction last night. Of the 21 cards I tracked, 7 were within 10% of my estimate, 4 were below my estimate, and 10 (almost 50%) ended above my estimate. To me, that signals one of two things: (i) I am not good at estimating, which may be true, or (ii) the results in REA last night were quite strong.
Of particular note, Wagners are on fire, with every Wagner I followed ending at or above (sometimes substantially above) my estimate. Look at the M116 blue Wagner SGC 3, which finished about $4k higher than the blue SGC 3 Cobb -- Wagner outpricing Cobb in the same card and grade is not something you normally see

Your 10% advice came in handy last night at REA. There were 2-t205 upgrades for my set, one of which was something I never thought I'd upgrade. I thought I was out and then remembered our discussion in Chantilly a year or so ago when you said that if it was within 10%, it was a good idea to just get it since that kind of thing likely never comes up for auction. So I placed one more bid which fell within 10% of my number and won it. You can likely guess the card as I don't have many t205s I can even find to upgrade!
On your original comment, I missed on the under but as you've said, the Goldin Koufax was the question. It will be interesting to see how they compare. I have no idea which is stronger or if they're the same but I take the under there. We'll see!!
