I have been playing go for a few months now and am about a 14-15k and i got there pretty quickly. i took a month off from serious play not because i wanted to but because i had to. once i came back i droped to 27k and quickly jumped back up to 15k-16k but this doesnt seem right because i have been studying and played once in a while so i wasn't out of practise and i know from how i play that i am much stronger than i was when i took a break.
