comment Data plotting to estimate answers
What you're talking about is trying to fit a function according to partial data. There are many ways to do it, but the most important step is to assume something about the structure of the function. Do you have any reason to believe that the function $t(n)$ (where $t$ is the time and $n$ is the stage) is polynomial (i.e. linear/quadratic...)? or exponential? or logarithmic? or what?

comment First Order Conditions
This is a very complicated expression to decipher. If you could produce a minimal example that shows where you're stuck it would motivate users here to help you.

comment How to change the expressions in terms of a specific variable?
Your question is unclear. Isn't the answer simply given by your third equation? That is, $$h=2y$$

comment NDSolve with initial condition: initial conditions did not evaluate to an array of numbers of depth 1(for 1D) or 2 (for 2D) on spatial grid
I would recommend to create a minimal example showing the problem. This way your pretty likely to find it yourself. For example, on my machine, if I delete the WhenEvent onwards, and work with the default options of NDSolve, the problem disappears.

I don't quite understand. Isn't the output of FindPeaks exactly what you're looking for?

I think a more concrete example will help us greatly in helping you.

comment Replace expression, but only “outside” of a function
Thanks. But lists of replacement rules are executed consecutively, so this will not work.

comment How to solve ReplaceAll problem inside Manipulate
A good habit will be to create a ''minimal working example'', that is, reproducing the problem with as little superfluous code as possible. This greatly increases the chances that (a) people will take the time to answer your question (b) the answer will be relevant to other users, and (c) you'll solve it on your own by trying to reduce the code.
