We are currently working on a new credit system which will ensure that everyone is awarded a fair amount of credit. The current system is failing as some users are receiving far more credits than others for the same amount of work.
To fix this we will predefine the amount of credit for each workunit. The amount will be based on a multiple regression of previous results from my own trusted hosts. It will likely be ready early next week.
Thanks to everyone who has pointed out these problems.
I have hidden all other posts in this thread. Most posters have not broken any rules so please do not take offence this. We are switching to 1 credit per WU later today while we wait for the new system.
