This is probably because some tutorials are based on the original mod they were based on, the OLC Gui for SH3. The creator OLC decided that it was easiest with his mod to read of halve of the marks, instead of all the marks. Iirc in the earlier versions of his mod he doubled the mastheight values in the recognition values to make the RAOBF wheel scales align better. In later versions he avoided that with requiring only halve of the marks to be counted.

But with so many different derivatives it's risky to rely on the precise procedures shown in these tutorials. Always go with the instructions that this mod comes with.

As the lock-on point for the periscope could potentially be offset from the model center (if some modder messed up his model offset) I would count all the horizontal marks, and divide by 2 if needed. Only considering the marks on the left or right side of the horizontal scale is risking false measurements leading to false AOB.

When finding the ships speed by timing it while it passes in the scope, should the scope be at 1.5 x zoom or 6x?

Doesn't matter, the line is dead-center of the view in both cases. And to null out your own speed effects, the periscope should be pointed 0 or 180 degrees, and the bow/stern turned just in front of the targets passage. Choose the zoomlevel that gives the best view on when the target bow and stern cross the line. So for distant targets this would usually be the high zoom level.
