Perhaps you should tell every car magazine that and nearly every other tester out there that use the 1ft rollout feature.
1ft rollout IS accurate...... if it wasn't then my drag slips and vbox runs wouldn't match (as they do).
Care to explain to me technically why 1ft rollout on these VBOX's isn't accurate for anything other than drag times.
I ALWAYS state whether my times are with 1ft rollout or not, so it's not that I ever hide anything.
Nonsense, no one uses 1ft rollout. Who has ever told you it's acceptable? We have had this discussion before Shaun and it's clearly went in one ear and straight out the other. I've been using vbox and visiting the dragstrips for over 10yrs now, very well known in the VAG community and have tested this extensively.
Racelogic themselves state that it affects times by upto 0.3secs

No one uses it apart from 1 US based car magazine called Car & Driver. They routinely post up quicker 0-60's than every other tester but they do say that they activate 1ft rollout.
The reason that it is not accurate for 0-60's is because it doesn't start the capture until 1ft has elapsed. On a dragstrip, you line up at the Christmas tree 1ft before the timing beams detect your wheels and the timer starts. It's an actual impossibility to have both an accurate 0-402m time and an accurate 0-60mph time, it's either 1 or the other dependent on whether you have 1ft selected or not.
If you have 1ft enabled for a 0-60/100 etc, you are not measuring from 0mph, you are measuring from 4-5mph as by the time you move 12 inches, you're already doing 4-5mph. The 1ft rollout enables this.
Who has ever told you that 1ft is acceptable for 0-60 use? Simon? it's bollo*ks, I've been in the VAG race scene for over a decade now and also involved in the GTR scene too and no one uses 1ft rollout for anything other than use on the dragstrip.
Your lack of knowledge is evident by your quoted words here...
1ft rollout IS accurate...... if it wasn't then my drag slips and vbox runs wouldn't match (as they do).
Yes, exactly, that's what it's supposed to do. It's accurate for drag strip use where you get a 'free' 1 foot. In a 0-60 test, you do not get a free anything other than cheating by 0.2-0.3secs.
Your vbox chart display clearly shows this when you plot in vbox tools too and even the corrected software will show that the clock doesn't start at 0mph. With regards to the vbox correct correction, yes, it is very useful as it corrects for slope, however, as far as I know this is not a racelogic endorsed product. In terms of vbox tools, you can plot heights in order to rule out gradient changes but yes, I do find the vbox correct tool useful.
Sometimes its best just to sit back and listen to others sometimes Shaun. I remember having this discussion with you on another forum, you're the guy that's taken his Audi RS to a Nissan GTR specialist instead of an Audi RS one.
If you want to come back at me with why you believe it's accurate, I want to see facts and evidence of this rather than the "well some mags use it" And no, no manufacturer uses a cheap £250 device to time their cars with and they certainly do not use 1ft rollout, otherwise known as
dragstrip mode.
There's a big thread over on GTR forums about the use of 1ft rollout in their leader boards threads and it IS NOT ALLOWED.
Switch it off for 0-60's, switch it back on for dragstrip indications. I don't mean to sound rude but we have done this all before.
one of the guys in a modded Mk1 Golf Gti (who was pretty rapid tbf) said it sounded "insane"!
