Toga II 1.1a has rank 5 in our list (I guess you refer to the "All versions"
list here), and Hiarcs 10 Hypermodern has no any rank, because its brother
Hiarcs 10 (default) performed slightly better. So there is no "4" next to
Hypermodern, it simply has no rank, so you compare it with the others by rating
only.

You can't use this logic to say that one engine is stronger than the other. Even
if one engine has intervals +10 -10 and the other +100 -100, you can't say the
first one is stronger if they have the same estimated rating. With more testing
it may turn out stronger or weaker, there is no way to know.


>I my eyes Toga 1.1a should be now on place 4. Where I am wrong?

"Hiarcs 10" (default) has rank 4. Toga 1.1a has lower rating so its rank is 5.


Best,
Kirill
