Max system % Drawdown during Optimization

["Sharps_45_70" <sharps_45_70@xxxx>]

I know this has probably been explained before, but I couldn't find 
it.

I understand Max % Drawdown for a single stock, but in the results of 
an optimization when you are optimizing over several (or many) 
stocks, is the Max system % Drawndown the average, sum of all, or 
max of an individual stock within the group? 

Thanks,
Ed
