It is an odd limitation. But what's even more odd in my opinion is why Lending Club does not extend that chart to completion. In reality, if you ever intend to put your hands on that money again one day (you know, actually spend/use it), your portfolio ages will eventually become anywhere from 36-60 months [technically about 53 months to date (since May 2010)] and everywhere in between. But that data is not shown for those accounts. I, for one, would like to see it. Not that it's potentially some riveting nugget of secret data or that there are a lot of accounts of that age yet, but I'm interested nonetheless.
