injector duty graphs

just a quicky:
when i was logging my car on the road, all i saw was 'injector pulse width' wondering what duty cycle i'm at. after talking to HumpinSS again (thanks man!), he got me an equation:
duty(in %)=pulse*rpm/1200
so i made up a quick graph for it:


it's also useful to look at it a different way:


so according to this, when i got to 21.5ms pulse @ 6100rpm, i was at about 109% duty cycle. not good. looks like i might put in the new injectors this weekend, so hopefully i will not have this problem anymore.
we'll see.
