How accurate is the lap timer?

You can set it so it starts from zero as soon as you start moving. Been using it with video to get some 0-60 times. I know not the most accurate method but better than nothing. Also, any lag with the speedo? That would obviously affect this scientific test.

How do you set it up to do that?

if you flip through the settings, there's an option for it. I forgot which one.

Trouble is, 60mph on the speedo is around 57mph real speed so you will only ever get a rough idea. The lap timer is built to record lap times not the 0-60 speed.

My speedo is spot on accurate according to a radar gun.

How accurate is it during acceleration though? Mine's accurate at cruising but not sure I'd trust it at any given tenth of a second point during wot.
