If you are referring to horizontal rotation degree position, my opinion is they are ok. Vertical height is mainly fixed by spindle shaft and a spacer washer. The cut height of course is a bit affected  that way. A bent down/up blade, usually can kinda eye ball that, sloppy spindle mounting, or bad bearings would show up in cut appearance as well as bent or damaged gauge height wheels. Anyway it looks like it  has all going good!!! "Have a great day every day"

Rotational position is not factor on these belt driven 3 blade decks.   Only the 2 blade gear  drive decks need to be positioned correctly.
