Regarding the Extraruum hybrid bar tape,
when wrapping with the initial inside-drop method (starting the wrap on both left and right sides toward the inside of the handlebar)

on the right side, the finishing edge of the bar tape becomes perfectly straight

on the left side, the finishing gets a bit offset front and back. Since I didn't have images of the wrapping technique at the left bracket,
I took some new photos.

↑This is the left lever of a SRAM 11-speed eTap (electronic shifting system). For the first time on someone else's bike, I wrapped it with the bottom-side technique.
At this point, the bar tape finishing is offset front and back, but

with one more wrap, the offset part gets hidden.

↑The bottom finishing is just one wrap on top of the bracket,
depending on the position of the bar tape edge on the bracket,

one or two wraps can be hidden by the bracket cover.

This is a separate case—the left lever of a SRAM 11-speed Rival that I wrapped previously using the top-side technique.
Although the bar tape edge position on the bracket is a bit forward compared to the eTap earlier,
the bottom finishing has two wraps.
The indentation in the bar tape is there because

this shape on the back of the bracket is being pressed into it.

Depending on the shape of the bracket cover,
in this case, just barely,
the bottom finishing slightly protrudes above the bracket.
So the ideal boundary might be "one wrap of bottom finishing on top of the bracket,"
but in that case, the length you cut at the bar end side becomes very precise.
Since the situation varies depending on the lever type,
if you're wrapping this bar tape yourself, please use this as a reference and adjust accordingly.
