[Is duration guaranteed?]

Thank you for your replies! Does it make any difference whether the animation is run in IFrame or not? Seems like my animation starts acting weird only if I run it from IFrame.

[Is duration guaranteed?]

Hello everyone. I'm working on some animation that very much depends on the accuracy of delay and duration. And I really would like to know if GSAP guarantees accurate delay and duration time for animation? Is it possible that animation duration can have delays itself, meaning that it will take, for instance, 1.01 seconds to complete instead of 1s:

var _duration = 1, _delay = 3;
TweenMax.to(item, _duration, {css: { opacity: 1}, delay: _delay});

Thank you so much!
