Excellent article Bret.

Thanks!

Great reading Bret.

For this reason, I double crank each string on my lockout tensioner. After pull the string, I'll go release the clamp and get it ready. But before clamping it, I'll keep my left hand on the crank handle and the right thumb resets the tension clip. Obviously a little more crank/tension is required. This simulates the constant pull action. And then I'll clamp the string.

The entire process takes another minute or so but I'm still able to string under 20 minutes.

Good idea! Maybe the next generation of cranks will do it right in the first place. Pull the tension to + 10%, and then drop back to the desired poundage. I notice the Wise unit does that (couple of pounds) even when it is not in prestretch mode.

Increasing the tension on an existing crank machine by ten percent would accomplish the same thing.

For the record, I don't think electronic machines could be described as more "accurate", just different. Arguing accuracy about something like this is useless. For what it's worth, an argument could be made that electronic machines should pull at ten percent less to more closely replicate what a crank tensioner does, since cranks have been in use so long that they've become the standard. I'm not advocating doing it, just mentioning it.
