Dragy Performane Meter - Baseline Testing

I went out to do some driving in the Mustang and decided to get another baseline performance test on the car using the Dragy.  The car is largely unchanged since the last test except I swapped the fuel filter and confirmed the throttle opens fully.  The car has 3/8 tank of gas.  I made four runs but the Dragy only logged one of them.  The 0-30 was faster but otherwise the times were largely the same.  

 
0-30 2.85
0-60 7.91
1/8th 10.20
Quarter 16.44 

The previous time I did this, I left at about the same RPM (2,000) and shifted around 5,500.  That is the same approach I used for this test.  My results from last time are as follows:

0-30 2.96
00-60 7.98
1/8th 10.04
Quarter (EST) 16.1 - 16.6

There is quite a bit to do here with a starting 0-60 time of essentially 8 seconds and a quarter mile of 16.44.

Looking at the second, quarter mile graph, you can see that I'm letting off the throttle before reaching the quarter mile.  I think it isn't a great deal faster but the quarter mile time then isn't very accurate.  I think I'm likely closer to a 16.1.  Ultimately, since I'm just testing on highways around town, I'll need to consistently focus on 1/8 mile or other data points as I'll no doubt soon go fast enough that a quarter mile time is completely impossible.
