It probably would be good information, especially for resource gatherers. Hey, if people want to do that math, then they have the upper hand. They can do calculations and try and rake in the most resources they can. Personally though, I think it's all random. On my other account, I have 90 WC and yet still I don't seem to get that many logs in comparison to other yew cutters, or even that characters 74 mining sometimes doesn't measure up to someone with 60 mining.
