Joe, the key is knowing your car and chute. On my setup, if I pull the chute as I enter the first trap, it is to soon. In these pics I pulled the chute as I (the drivers door) passes the first timing cone, this allows the chute to "drop" before the car gets to the finish traps (but does not slow the car) as the car powers past the finish then chute will then fully deploy. What we see here is what I should do all the time.
At Loring, I was going faster and pulled the chute sooner,, It slowed me down before the lights. Going faster also means you drive away from the chute faster,, so I should use the same exact procedure all the time. Pull the chute as the door passes the first traps.
Here is the video from Loring. I was going 180 mph when I pulled the chute. If you go full screen you can see the first cones in the lower right, and you will see the chute drop out just prior to me entering the cones, you can see at that speed the chute depolys rather fast even though it has long lines. The chute fully blossomed and slowd the car before it got to the final timing line (this slowed the car from 180 mph to 175.250) So now I wait to pull the chute till I pass the first timing cones.

Hope you and all my other LSR friends had a good Holiday weekend.
