Well, some people know how to trade and some people know how to analyse. I am the latter and I believe I can glean a great deal from statements. The statement not only gives you the outcome but also the context. It's a matter of connecting the dots to see a full picture, or at least the impression of a full picture. For instance, it's not difficult at all to work out the draw down from the open price and the close price. You just need to furnish a chart in between the 2 points if you know roughly when the trade is done.
There's also a psychological dimension to statements. Even if these are not produced, they nevertheless reveals something. There is probabilistics in the art of analysis, and not just in trading.
