	Please introduce the BOINC RAC Decay function. The majority of the leaders shown under "Leading Participants" haven't contacted the server for a very long time. Most have not contacted the server for a least a year and some have not contacted the server for over two years, yet are still being shown as contributing tens of thousands in credits when they are not. It would be nice to able to see who is actively contributing to the project. Thanks Conan

	It would be nice if the RECENT Average Credit was actually that. I was trying to find some hosts to compare to mine. Out of the top 100 hosts only 5 had any tasks listed and 4 of them were all aborted tasks. The only one that completed any work was in November.

	Please turn the RAC DECAY function ON. Without this function, the stats are completely misleading.

	It has almost been a year since I posted, this problem still has not been addressed. Your stat list is null and void, meaningless and leads people to think that you have heaps of people producing results when a lot of them have not contacted the server for more than 2 years (e.g. the currently listed number one producer). Please enable the RAC decay feature in the BOINC code to correct this and help show who is currently working on this project. Thanks Conan

Thanks Conan I wonder if that is something that drives people away from this project. According to BOINCstats: Users 6,202 Active users 371 (5.98%)

	Very irritating - I agree. It's my impression that the decay function for a host is activated every time that host is allocated new credit. No new credit, no RAC decay ! It's a significant overhead to scan regularly (daily ?) all hosts and calculate decay for all those that have not been decayed since the previous scan. Does it really matter ?
