Its really too much to ask anybody knowledgeable to believe a test that a manufacturer does comparing their engine to a major competitors. What would you expect Horizon to say: "Well, we tested the Saito 100 vs. the OS 91 and the Saito was hands down the better engine - of course we are not the least bit biased in any way whatsoever and are completely neutral with no conflict of interest in these matters." Yeah sure.
