Help reading trailing plugs

I'm sure this is a common question but searching hasn't turned it up.

Car went through a few heavy flooding sessions before I got leaking injectors under control.

My trailing plugs were fouled / filthy with carbon on 1/2 of tips.

Is this typical, or does it point to any other sort of issue I should be planning for?

Trailing plugs (at least in my experience) get a little more build-up than leading, probably because they're less exposed and shrouded a little. Your probably fine. Stick a new set in and check them in at the next oil change.
