Track condition photos

At some point in the near (1 year) future I hope to purchase a small track loader, Deere 350/450 or Cat 931 size machine. From reading in this and other forums I have learned what a good vs shot sprocket looks like. To measure across "x" number of pins after you have backed up the machine to stretch the track out and consult the chart to determine track wear and that a quick look at the idler position can reveal a rough estimate of wear (assuming the correct number of links)
My questions are about idler wear and carrier wheel wear and what the photos are telling the prospective buyer. Attached are 2 photos, I would appreciate observations about what they are telling me.




Thanks,

Rick
