.phil.dpt and I were discussing the Voltra compared to the Tindeq in it's accuracy. He came up with a solid test that showed they were relatively close when testing around 100 lbs. We've been seeing bigger discrepancies but as I reflected on it, I noticed it when people were smashing knee extension goals. So I wanted to see if the discrepancy increased as the force output got higher like I suspected. TL;DR the Voltra reads around 5-7% high with sub 100lbs and climbs consistently with > 13% once you start getting north of 200lbs. Phil made a comment that he wanted to test 200lbs as that's the top end for the Voltra but the isometric settings actually let you test up to 400lbs. I mention this not to correct him but because my initial concerns were that we deformed the load cell pushing past 200 lbs and it would appear that's not the case as we've never touched even 300 (š¢). The Voltra is awesome, we still love it, but there are some weak spots that need to get fixed if it wants to be a legit testing apparatus.
