He did not say that there are not engines that suffer at long time control like Genius or Fritz5.32. His point is that he rejected the excuse of engines that they are weak in blitz that they need long time control. If aristarch has better branching factor than Fritz5.32 then it proves nothing because Fritz5.32 is an outdated engine. Aristarch is also clearly not an example of an engine that is better at long time control. see http://www.innconx.com/~wildcat/bullet/Ratings.html Aristarch is number 3 in the 1+1 time control list and has better rating than engines like Crafty or Yace that are also at similiar level to Fritz5.32 Fritz5.32 like Genius or Hiarcs7.32 may be an example for an engine that is relatively weak at long time control because of bad branching factor or bugs.
