This doesn't stand from physics point of view. You can do 100 pulls at 50lbs, the tension will still be 50lbs... The only thing that changes, especialy with polys, is that you defacto performed a prestretch, so the drop in tension after the stringing will be less.If it takes you 4 attempts to get near parallel vs 1 attempt, you will have different final tension as you've completed additional pulls on the former attempt vs the latter.
Neither. It is an arch, with the "high point" being horizontal (point furthest away from center. Esgee is saying if you are 10 degrees off (+ or -), you are at 98.5% of reference tension. That percent would go down (less tension) the further away from horizontal the bar is. A DW can't tension a string MORE than the ref tension the weight is positioned at. It can only be AT or below, depending on the position of the swing arm.So is there more tension on the string when the bar sits above horizontal or is there more tension when it sits below horizontal?
Interesting......if you are 10 degrees off (+ or -), you are at 98.5% of reference tension.
Very interesting...A DW can't tension a string MORE than the ref tension the weight is positioned at. It can only be AT or below...
So tension was the same in all 3 positions?I was curious of this and did a test with my Stringway ML90 a couple years ago, which is supposed to be able to give around the same tension regardless of angle.
Yes. I tried to make it have as much various as possible. (e.g. as low as possible without it touching the table)So tension was the same in all 3 positions?

Theses statements apply to different systems, that work differently, so there is actually no contradiction.This seems contradictory. Shouldn't the resulting weight be off then?
The Stringway system claims to be able to have the tension bar at various angles and still pull the same tension.This seems contradictory. Shouldn't the resulting weight be off then?
No math or physics necessary...
When I had a dropweight... I used a luggage scale and Kevlar string to test this. With my machine (Alpha Pioneer DC plus at the time), I really don't have to nail it to perfect horizontal. YMMV with your machine.
That said... with a ratcheting drop machine... it may not be possible to get to spot on horizontal
. . . did you have a Gamma DW? I have a Kmate, so there's no ratchet mechanism. I can get spot-on parallel. Does the ratchet gearing mean the weight can't be so micro-adjusted?
True the closer to horizontal the closer the tension is to set reference.It's really not important if you're not concerned with the tension. Too high, the tension is too low. If you let it drop lower than horizontal, the tension is too low also. It just takes practice.
