It sounds like you could be talking about one of a few things.
If you're talking about where it says "Choose one that has a frame between 1 and 5, 1 being the most preferable", that's a choice that's up to you. It just means you'll have to make a few phone calls before you put your egg in.
If you're talking about where it says "Don't move. What was your frame?", that's referring to the frame you picked in RNG Reporter (the one I just talked about).
If you're talking about your frame in-game once you've hit your delay, you can just assume that it will always be 1 when you start up your game. You only need to advance it by making a few phone calls (if the frame you chose was higher than 1).
