Just one other thing to keep in mind about rev-rates, is that not only is it relative to oil volume and viscosity, it is also relative to the rg and diff. of the ball of choice, as well as the surface of the ball. Low rg high diff. ball will rev up easier, giving a higher rev-rate than a high rg, low diff. ball.
The most accurate testing should be done with a med rg, med. diff ball on a medium length pattern with a medium viscosity oil on a medium friction surface.
Since all stars and planets are not aligned for this type of testing, the most important thing in my opinion is that your revs match your ball speed.
