I think 30% is way too much "bonus" to give to someone who may have only just beaten your score or you couldn't quite beat theirs. Around 10-15% is enough of an incentive to improve your score beyond theirs without overly penalising someone who came oh so close.(posted 9688 days ago)Definitely drop any scores who's raw score is < 25% of the top score from leaderboard scoring.
With this new system there is definitely more incentive to improve scores on games where while you may not get a better score than the current high you can greatly improve your points ranking.
Well done Zwaxy.

PS: I favour the look of 10% but maybe 15% is more appropriate. We'll see what the majority think - but count me as definitly thinking anything > 15% is too large a "bonus" for 1st place.
