It's a known fact that LCD hardware with Ti-83/84 screens is not consistent. That is, even if one screen requires only 65 T-states between delays, another may require 70.
However, is the delay consistent for the particular screen? That is, if an LCD for a particular Ti-83+ requires 70 T-states, will it always be 70 T-states?

Well, about that. The number you find is the maximum number of t-states you have to wait until the screen is ready. In reality, the actual number you have to wait varies by quite a bit. For instance, I made a program that tracked how many t-states the screen needed at that moment in time. What I found is that the amount needed was random and was spread out over about 20 t-states. This means that the 70 t-state screen will actually be ready to go in 50 t-states occasionally.
However, the short answer you want is yes, once you find the delay, it will never change.
