Just to let you know we are just going by the info you have given us and assuming a lot. At least I am.

Because there is no video of your run for us to critique, we are assuming you can launch and shift. 1/2 a second or more can be made up with a good launch and proper shifting. Yes, not all of us are as quick as Ronnie Sox when it comes to shifting.
