Hi Matthew  
  
  
  
after downscaling a system the stats show a completely wrong realism factor.  
  
  
  
e.g. AT Forex shows a realism factor around 270%. In reality this system collect very small pip-gains as often large slippage when entering a position. The slippage is often higher than the trades gain which results in a loosing trade for autosubscribers whereas the trade it’s displayed as gainer in C2.  
  
  
  
can you please implement realism factor recalculation after system rescaling?  
  
  
  
Thanks.  
  
Lukas
