2H = heart stopper, may have spade stopper
2S = spade stopper, denies heart stopper
2NT = undefined
3 our minor = good raise, constructive to a bad limit raise
3H, 3S = splinters
Gameforcing raises go via splinter or a stopper show, and 2H and 2S are forcing to 3NT or 5m. A direct raise to 4 our minor is RKC for the suit.
As you can see, there are holes! How to fix the holes? We want to keep the stopper shows because frequently 3NT must be intelligently reached if it is there. If you are going to say "Your system sucks", fine, but in that case have the heart to give a better one that is complete
