I return my flips about twice a year. My guess would be at least half or more don't return flips, so the pop reports would all be a bit on the high side of estimates. My fuzzy math for pop reports is to take the pop number and subtract 20% from that number to get probably a more real number.

On some of the more scarce to rare issues, I feel the numbers may be a bit more accurate but probably a tad high.... As the years go by and these cards reside on the registry, I still think they provide invaluable data on just how rare/scarce some issues might be....

We have discussed this before, but if you take the Pop number from PSA, SGC, and BVG and then guestimate the raw number range, you can get a pretty good feel for just how many of a certain type of each player may be out there.
