I had proposed this in another thread a couple of years ago. It brings strategy into play, it doesn't allow any misses so it doesn't add to the time element, and it would actually allow you to plan, time-wise, more accurately if you plan on an average of 4 passes per competitor.
I would also propose you can run any line length as many times as you want; but, you only get a maximum of 6 passes. If you fall on a repeat rope length you are done. So for example, you could go 28, 32, 35, 38, 38, 39 - done! If you ran the 39 you would not get a shot at 41, this is where the strategy comes into play. If you fall on a repeat line length that you typically run, too bad-you don't deserve to continue.
Bring on the haters for us innovators!!
