This is my favorite episode so far. I have a very similar system to Andy's (exempt on a much smaller scale In volume and price). It is nice to see my system is not as crazy as I think it is.
Instead of ranking my art on a spreadsheet like Andy, I have a more visual system. I have a pic of each on my iPad. I rank each piece by placing the pics in order top piece to those on the trade/sales block. Like most my rankings change often, but it is easy to "drag" the pic up or down the list.
I find this process helps a lot with buying a new pieces. I can easily see about were a prospective piece would be be top 10, top 20, bottom 10. As an example I may spend 4 figures on a top 5 piece, but may spend only 200 on a top 50. This helps me justify or pass up a price quickly.
Thanks for the podcast Felix and Andy!
