Limit on adhesive ripstop tape patch size?

[uer16 1]

A canopy I have was dragged against something sharp in the trunk of a car during a break-in, causing a pinky-sized hole, and a bunch of abrasions/pinholes over a certain area.

I would avoid putting a full-sized patch since it's an older canopy that's worth as much as a patch or 2 would cost.

I do want to jump it for the next ~200 jumps, and want to use ripstop adhesive tape for a quick temporary-ish repair.

The bigger hole is no problem, parachute rigger's handbook says "For
holes up to .5-inch in diameter or a tear, a double-sided
patch is necessary", and the hole is smaller than that.

I'm more worried about the pinholes/abrasions: it would require about a 10" piece of tape to cover the whole area, I believe one-sided would be sufficient. Are there any issues with that much tape being applied to a canopy? Would it be a good idea to just not do anything and see if it becomes worse? Remember the "repair" only needs to last ~200 jumps at which point the canopy is a car cover.

The hole+abrasions are on the topskin of an end-cell near a non-loaded rib if that helps.

Years ago I had 2 long pieces of tape on a canopy with F-111 type fabric (not zero porosity) that had large friction burns. It lasted a long time. Just replaced it if needed.

Double-layer patches last longer ..... more than 200 jumps.
If you want to get fancy, ask a rigger to sew around the edge.
