Question and picture 1932 floorboard anti squeak .

[37 Coupe]

I have the main board and the thin anti squeak/weatherstrip ready to tack on but have a question. Do you tack on one long strip that corners around the back edge to sides or three strips? Also do you just trim the side edges or wrap around entire width of the side edges and tack to bottom? My question is because the boards are already relieved on side bottoms ? Not even gonna ask on front board yet just want to get this one going.
