A lot of times I come close to hitting a PR, but don't quite get there, or I don't get even close. Regardless of how near or far I am from that PR, I would still like to see where I fall in terms of 2nd, 3rd, 4th fastest, etc. Being able to compare to more than just my PR would be really useful for tracking progress.
And ideally, I would be able to see a list of ALL, for example, 5K times... So if I run my 100th fastest 5K some day, at least I know how far I have to go to get back to my peak.
