It does not matter, that R was used, because it is already stubstituted,
but I now use lower case r to avoid possible doubts

You may try lower case L = 1 .. 100 in your sheet

Here is my sheet: asympt_problem2.mws

Edited: L = 40 .. 50 (in your sheet) locates a problem (the first plot in it)

I "know" similar stuff from Financial Math, but not stemming from Physics
it does not illuminate me :-(

Roughly there are 2 models I looked at: one is  normal inverse Gauss and
using Bessel functions (AFIAK it is motivated by vapour), the other was by
using a characteristic fct approach).

Can you provide some steps before your formula?

@kh2n 

it does not matter, that was not used ...

Instead you *may* try to use some order 1 (not order 0)

Or better: break up your expression, so it has a meaning
(as it was probably built) and study that.

Where does it come from, what does it mean?

I mixed up while dividing :-(

Anyway, find it attached Kopie_von_R3Infintyp.mws

Ok, works now, but I was not able to make substantially shorter
by the usual attempt (around (making it rational) simplify, combine etc) :-(

You may also try

with(codegen);
makeproc(Q, [x,t]):
P:=optimize(%,'tryhard');

P(x,t) is a bit shorter ...

Note, that you are working with 10 Digits only, you savely can increase to 15.

the sorting of answers done by the board software distroys all the sense they certainly would make

BTW: is there any command in Maple to produce a random tree without using that board?
