Nope.. thst works.. you can also start high and move low, especially if you've cut long,
Either way, it's fairly tedious (that "work through a few cycles") if it involves hoisting and lowering the antenna. (At Field Day, we used it for the GOTA station on year, and there, it was easy, because we had 4 people.. one on the meter, one on the hoisting line, one on each end of the antenna. took about a minute per iteration, so in 15-20 minutes we were done)
Doing it with just the SWR meter and rig is quite tedious, esp if its the kind where you have to "set" the fwd power reference (like my old FT-757)
One advantage of this kind of antenna is that it's truly a scrounger's delight. All you need is some wire and duct tape. (Why yes, that essential tape that serves as wire separator, and center strain relief/mechanical connector, AND as something to cover up the bare wires where you've twisted them.)
