Thanks guys. I've been planning to do some tests once I get a MID and this is how I would carry them out. Doing so many runs may not be necessary, but I think establishing the baseline is important.
If your difference between runs is huge then obviously your driving or other elements is interferring. You need to make certain your driving is consistent when testing. So, the first thing I will be testing once I get a MID and get it calibrated is...ME!
