I was describing the follow-up post-patching check, not the initial bubble check. On the first pass, yes, I go all the way around and clearly mark every discovered hole. If a tube has more than two holes, I usually discard it as the economics of patching goes way down (I consider Slime a hole for this evaluation, as it can temporarily mask holes and gum up valves). Exceptions can be made for uncommon or hard-to-find tubes.
