I see that you guys initially presumed the finish point was when the screen turns white whereas I had made it the point where the glass fades out.

Seems like the way you initially did it seems more logical as it is easier to pinpoint the exact moment the screen turns white. I am happy to change it, unless you are fine with the way it currently is?

we are fine with the glass fades out it works well

Yes, it's good as it is! :)
