I find that list really dubious -- it's very hard to believe that 97% of Ron Conway's investments have worked out. The only way I can imagine that being true is if there are strings pulled so that there's a fire-sale at the end that's being counted as an exit.
Right, as Paul pointed out, the numbers for Conway are way low (maybe these are just the SV Angels numbers?), but over the course of Conway's investments in the last 20 years, it's astronomically unlikely that 97% of them are "not dead".
