Yeah, i think it was a few years ago, where Max Mächler released stickers to fix the wrong caster etchings on nearly all available setup systems. Not only SkyRC, GForce etc. were affected. Also Hudy made in that time a running change to fix it. Besides that digital gauges, if the Display isn't crap, are easier to read most of the times and avoids the parallax error
Before i bought my hudy setup system, i had a SkyRC one. And i couldn't get my Car to drive straight for the life of me. Turns out each of the 4 corners of the setup-system was setting different Camber, Toe and Caster angles, but showing the correct ones. Only after a buddy controlled my setup with his setup-station, right after i was done with setup work, he asked if i was drunk while working on my car because every corner showed different values.
Most likely a isolated case, but i was about to loose my mind
