Good for what? Unless you can tell us teh way you were running it, we can't tel you anything about the way the bike is running.
For example., let's say you puttered back to the shop after doing a plug chop. What we are looking at is the putting back to the shop and yet we think we are diagnosing WOT on the main jet. When people ask me that at the race track, if they didn't do a full bore plug chop, I'm going to start throwing their plugs away until they learn that you can't read a plug just by looking at the tip and you can't read anything unless we know exactly what was happening when the ignition was killed.
I don't mean to be a PIA but plug mixture is read down inside the plug, not at the tip. The tip tells us if the plug has been too hot from too much advance and too little gas, but that's all it tells us. The insulator nose should be white with no signs of pepper spray (detonation) or cement boil.
Plugs have to be running at peak temps to self clean and to read them. Partial load masks most things we need to see at WOT.
If that plug was pulled after a full load plug chop, it's running too cool. If not it cant tell us much. How does the bike feel? That's more important
