That's why she's basing it on an average adult tree. Average would probably fair in the middle of tree sizes. Of course there will be trees that give you double the amount of logs and such. There's also another point to be brought up with the bows. I think the logs are priced for the bows and only the bows and not firewood or something. So splitting them wouldn't do much, but you can't even really make real bow staves from a straight cut log that we see in RS.
