How are trophies in Clash of Clans calculated? [duplicate]

I've practically browsed the whole Internet, but didn't find any particular formula for calculating the trophy outcomes in a PvP game such as Clash of Clans. This is what I figured out so far:

At some point I thought that the sum of points was always 48, and that it is separated between the winner and the loser, weighted in favor of the one with fewer points. This turned out to be not true, because I myself have been in battles where winning I got like 13 trophies and losing I got 14 (total 27).
I thought it is some kind of an ELO rating system, but couldn't confirm it actually is, not just because there is no negative trophy count in CoC, but also because in small differences in rank you could actually gain a lot of trophies (like 30) when winning.
As far as I know you're matched against opponents with a rank that is ranged within ~230 trophies compared to your rank
Ps: I'm not talking about clan trophies, but the trophies of a single person in normal multiplayer.

I'd like to ask that if anyone more familiar with the subject brang more light into this, preferably a Supercell employee. ;)

How does COC determine how many trophies you get?

The number of Trophies available to steal is based on the Trophy difference between the attacker and defender. If you attack someone from a lower league, you will have only a few Trophies to steal and a lot to lose. If you attack someone with more Trophies than you, you will have many cups to steal.

Is it worth dropping trophies in clash of clans?

Dropping Trophies: The most efficient way to drop Trophies is to start an attack and press 'Next' (but don't release it), then drop one troop and quickly surrender. You will lose the match and Trophies, but will move one to the next one without having to go back to your village....Low Trophy Farming.By:zombiebenderTrophy Level:0-2001 more row
