    You mean like this? Yeah, I see how that could be annoying. Let's not. pj chgo

    Spin-to-Speed or Revolutions-per-Foot?

    Except for you, apparently. Of course - but I'll do it with as much knowledge and understanding as possible. Sure - even if you learn it yourself. And knowing about spin to speed helps your understanding of and ability to produce those answers accurately. Yep, knowledge can improve your...

    Spin-to-Speed or Revolutions-per-Foot?

    I think everything you can learn about the game adds to your skills, even if you don't notice it. For instance, a more familiar way of expressing the amount of spin on the CB might make it easier and more accurate to visualize/predict the effects, even subconsciously. And just to be clear...

    Spin-to-Speed or Revolutions-per-Foot?

    Appreciated as always, Dave. So RPF = % of maximum tip offset X 2.1, right? So my previous post about thirds of maximum tip offset (linked above) shows 0.7 RPF, 1.4 RPF and 2.1 RPF for 1/3, 2/3 and maximum tip offset, right? I thought (for no particular reason) the maximum would be higher...

    Spin-to-Speed or Revolutions-per-Foot?

    It would quantify one of the variables so it might be better understood/used. Maybe I've already quantified it in the most useful way (in the old post I linked above): "X percentage tip offset creates Y cross-table kick angle". But I'm always looking for improvement... pj chgo

    Spin-to-Speed or Revolutions-per-Foot?

    In pool we use the term "spin-to-speed ratio" to describe the "amount" of spin on the CB, comparing revolutions to distance traveled over a fixed time. But the simpler way to express that would be "revolutions per foot traveled", ignoring the time interval. For a given amount of tip offset...

    I'm pretty sure the spin/speed ratio is entirely determined by how far from center you hit the CB. pj chgo
