Your KGS account isn't based so much off just your win rate but the rank of those you have won against. So even if you won a few games and stopped playing but those who you beat kept playing and gained in rank, your rank would improve. If those you are beating are staying 10k and not improving it'll take longer for your rank to improve than if you were beating people whose rank was improving.
