Points calculation in the SNG Leaderboards

ok another question on sng points how do your total points go down from one day to next im not talking about the average.im talking total won in tournys ive actually position for points and total went from 572463 to 567540 the next day.this total won NOT THE AVERAGE.this makes no sense

yeah but woudnt that mean a deduction for not placing.if it does im doing better than I thought lol also thank u Sharon for answers to my questions you have been very helpful

im getting it.thanks again.wish ya luck playin
