I think if you're going to do this should only accept dragy 1/2 mile slips. Otherwise no way to confirm it's actually a standing half mile. Every event I go to has different rules, lengths, etc. Shift Sector is the closest to accurate.

You can check the rules of each event if its really standing half mile... regardless to that is that dragy is allowing slope to +-1% which is producing some differences... If you want to have the most accurate result you have to go with perfomance box and correct that time with db scanner to 0 slope which is common in europe :)

The max -1% slope variance rule I think is more reasonable than applying a correction factor to slope which may or may not be accurate. Next time you run test the dragy and your VBOX corrected times side by side in the same car and we'll see if they are different enough to worry about.

I used to love the performance box but compared to dragy it's really subpar despite costing 3x more. The box itself gives inaccurate traps (doesn't average over last 60'), inaccurate time to speed (puts a 1' roll out on them), half the time can't find satellites, sometimes doesn't save runs on the crappy SD card, etc.

I will test soon with new Setup :=)

Nice! I'm assuming you chose to go from a stop? I think NFZ lets you do it either way?
