Have you tried using my timer at all? I don't mean to be forcing it on anyone but when I was making it, the idea was to make things as quick and as easy as possible to hit. I incorporated the fix that I suggested to you as well as a better adjustment system. If you use the same numbers that you put in pikatimer and the delay adjustment that I added in, I'm fairly confident you'll get it in just a few tries.
If you'd rather stick with what you know though, I understand. 'Twas just a suggestion.
