Glad you like the fact that it changes. I want to keep it as simple as possible so that it can reach a wider audience but for some reasons, it seems like ties are really hard to avoid (especially it the case of determining 5 places). I am having fun with the 5 players, I think its the best solution yet (and I don't want to copy @nanzo-scoop's time of earliest goal scored), plus it makes participants more aware of the league. You'll be happy to learn that It'll probably have to change again in the upcoming weeks when they will be only a couple of playoffs match-ups.
I totally get what you mean, just like you I prefer putting in efforts before I win something.
variety is the spice of life :P
