I suspect that in real world terms, there will not be a difference. However, as we can faithfully draw the mask and have it cut to Pavel’s original design I see no reason not to follow it. That is, keep the central bar a solid bar.
What do you think?

When in doubt go to the original. Here is a link to Pavel Bahtinov's forum. it is in Russian.

You see Pavel has a center Cutout just like my variation. The most important fact is that the slots are a mirror image of each other in respect to the centerline of the OTA.
