5.2mm = .2047238" Size of the plywood
3/16" = .1875" Clearly too small
7/32" = .21875" perhaps an option but it is hard to find this bit.
13/64 = .203125" Just a little too small doesn't seem like this would
leave space for glue.

You are calling out measurements to 5 or 6 decimal places. If you have a
13/63 bit use it and if you need to make the slot wider put a strip of
scotch tape on the edge of your router base and you will widen the slot.
You could also just file or sand a small bevel on the plywood and tap it in
the slot.

A router bit in a piece of lumber probably cuts a swath just a little wider
than itself anyway.

they come up with this striped stuff.
