No rule on how long your line is. By distance or time.
Of course the ground will limit the length of your downline. Just remember every manuever is a geometric display. Radius or turns or circles need to be the same. Roll rates need to be the same, downline/uplines need to be the same........this is all for each manuever. You can vary them in each different manuever but for one specific you need to keep things constant.
Oh---and have fun.
Might not be a specific rule, but the maneuvers need to be centered on the line. So a 45 degree upline with a half roll needs to have the same distanced on the line before and after the half roll. I just wanted to clarify this because counting was mentioned earlier and that might not be a concrete way to time it. I'm sure it works fine assuming you have a constant speed.
