If you move the ring till the objective is as close as possible to the razor, then make minor adjustments you may me able to get the max power into effect.

No such thing as the best razor, only opinion based on individual experiences.
I prefer TI's to Dovos . I prefer Bengalls to Invictas. I prefer vintage to modern. I prefer Iwasaki to most...

That may be a problem if the Dovo is not perfectly ground.... as most are. Any warp or uneven grind will not be covered without the X stroke.
