Golden, based on a Monte Carlo simulation and theoretical arguments, calculated the magnitude of these effects.  The results of his analysis are displayed as Golden diagrams.<ref>Golden, Les (2010).  “Countering the Casino Countering of Counters:  The Golden Diagram to the Rescue,” ''Bluff Europe'',  June, p. 84-85</ref><ref>Golden, Les (2011). “Trust Me:  An Undetectable Winning System For Blackjack! ,” ''Bluff Europe'', March, p. 94-95</ref>  He also suggested a stepwise betting strategy to reduce the effects.<ref>Golden, Leslie M.
