Log purchasers use many reasons for the differences in log rules. For example, users of the Doyle Rule, which underestimates volume in smaller logs, say that this is the very reason it is a fairer rule in that it costs them more to process smaller logs. This is logical since the logger will have to cut more trees, the sawyer will have to saw more logs, and the yard crew will have to move more logs to the sawyer, to equal the amount of lumber in much larger logs. However, if he cannot efficiently utilize smaller logs, he should base his offer on that, not on a biased estimation of yield. There are other reasons given to justify variance in log rule use, but frankly, none hold much water for me. As we can see, there is the potential for dishonesty when choosing log rules.
