Yes, mine too now. No gonna tell you the stupid mistake that made it not.
I am not so sure we have the OP's problem understood.
The requirement for one servo is to move, delay and move again.
I think (!) that the matter is how to make two servos both have an ability to move IN and OUT with adjustable times.
And all solutions, even the OP's example, simply repeat the motion; perhaps the state machine that handles making the servo moves should be designed to do one such move each time it is (re)started, on demand of externally determined conditions.
