In the given bidding context South has 3 ways to show support. 2, 3 and 4
I prefer to use this as follows:
A. 4 - complete junk
B. 2 – I have 3 cards support but no top honor in , any strength. This path enable to declare in some cases the only makeable game 3NT. In response to 2 , opener can: insist on by bidding 3 and serious V.S. non-serious bidding continue or search NT contract.
C. 3 – I have 3 cards support with 1+ top honor in , better than 4 (it is not a “serious” but unlimited )
in response opener bid 4 or 3NT or Q-bid. 3NT and Q-bid are serious or non-serious as partners define it.
IMHO The given hand opener should make a non-serious bid

I play that 2M 3M and 4M all show 3 cards support
2M deny any honor in M, any strength, this suggest NT contract. If opener continue with 3M(after 2M) we proceed with serious and non serious slam try ;
4M show very very bad hand ;
3M show Hxx or better and better than 4M. from 3M we proceed with serious and non serious slam try.

A simple definition with the same effect is:
I will rebid 2M with 5 cards in any of the following cases:
1. I have no values or distribution to bid 2nd suit in 2 or 3 level
2. If we belong to NT, it is better that you play it.

I am used to rebid 2M with 5 card major, but the answers “is the default rebid …” does not fit to my style.
My definition to 2M rebid with 5 cards is: I will rebid 2M with 5 cards in any of the following cases:
1. I have no values or distribution to bid 2nd suit in 2 or 3 level
2. If we belong to NT, it is better that you play it.

In the following sequences responder show 3 cards in a Major suit , looking for 4-3 fit
1-2-2-3-4;1-2-2-2NT-3-3-4;
What strength he needs to do it , can he do it with 10-12 only ?

You did not specified if you play Serious/Non Serious 3N after 3M.
I think it is a must.
The 2 bid looks strange to me as you do not have a biddable suit (5 cards suit or good 4 cards suit) , I would bid 2 over 2 to deny a biddable suit.
4 bid obviously deny spade control. Does it show slam interest or simply show his hand ?
IMO, the fact you have spade control which might be what partner is looking for is not enough to make 4 bid (LTTC) . If 4 was slam try I would bid 4 (LTTC) with that hand only if the Q in was a K. With the hand as defined i would just bid 4.

3 (instead of 2) sound to me as asking for stopper , direct 4 (if it was made) sound to me as shortage and looking for spade control. 5 sounds as if he has control and no control

As I said I was interested in the overall scientific conclusion based on simulation.
A list of advantages and disadvantages is not good enough as it has to be combined with probabilities.

i would like to suggest another option how to distinguish between 2M and 3M bid by responder. Both show 3 cards support.

3M - show at least one honor in M , bidding proceed from here as usual
(i.e. show: very bad hand /non serious slam try/serious slam try) ,
strength of responder can be any thing but he is better than direct 4M bid

2M - deny any honor in M strength of responder can be any thing
Opener equipped with that knowledge about trump quality of his partner continue the bidding as he wishes. That include the bid 3M. 3M show he is still interested to play in M and his partner will respond in the same style as described before.

The idea is first lets make sure if we have reasonable trump suit or not. If we have bad trump suit - NT should be considered.
If we have reasonable trumps we can explore slam if we are strong enough.
With the information he got opener is in position to decide how to continue the bidding and to which contract he should target
Same is true for responder who can sign off in 4M or explore slam possibilities by bidding 3M

I see that i made a mistake in the definition of how i play it , 3M by responder just show hand with 3 card support stronger than 4M, it can have regular values or extra values ( it does not show non serious slam try as i wrote) after the 3M bid i expect opener to define his strength or show control with extra
