[Shotimes] Re: G-TECH/Pro fun

[Donald Mallinson]

In my testing of a G-tech, and the Vericom, these devices 
start timing as soon as the car moves, and drag strips 
always have SOME room between the timer and the car moving. 
  This means that G-tech/Vericom/Escort devices should have 
a slower time than at the drag strip.

My tests almost always had about 1/10 added to the drag 
strip time for the G-tech/Vericom (haven't tested the Escort 
unit yet).

As for MPH, since the timers make a calculation at the exact 
moment of the end of the run 1320' (based on G-forces/time) 
the MPH on a G-tech device was always higher by about 1-2 
mph than at the drag strip.  The drag strip takes an average 
of your mph over the last...what ron? 100 feet?  50 feet?.

Other than that the G-tech/Vericom was as consistent as the 
drag strip.

Now, on the street, you have wildly varying traction and a 
lot more elevation change than the drag strip unless you are 
very careful or know a surveyer!

Running both ways and averaging over the same section of 
road is the best way to eliminate elevation/wind from the 
equation.
