New function: RankPosPrev

RankPosPrev([# of weeks]) functions exactly like RankPrev, except that it calculates the previous rank position rather than the previous rank.

If you use RankPos more frequently than Rank, this will probably be useful.

Nice add. Thanks.

Cool feature.

Thanks Great feature.
Can you please add RatingPosPrev(“RankName”,WeeksAgo[,sort]) that works like RankPosPrev(WeeksAgo[,sort]) but for other ranking systems.
