I share your concern Igor. I think most contesters do. I have no complaint over efforts to improve fairness in contesting, indeed I support and applaud all that are well considered and implemented. S
This will be my final post on this subject unless the RDXC committee suddenly relents; making available to scrutiny the elaborate analysis they claim to have carried out. I see little prospect of thi
Having myself met with unfair and unjustified treatment at the hands of RDXC adjudicators I can empathise with those claiming unfair treatment in adjudication. However in this case having looked at t
