Help me read the plugs

Alright guys. Need a lil help reading the plugs from my dyno run yesterday.

N20 is a .72 and fuel is a .36. Using a BR7EF plug. My set up is a forged 347 with LS2 heads, and around 10.5ish compression.

Strap is a light brown from tip of strap to just before it starts to bend.
Top of porcelain is a very, very light ash brown.
I haven't cut it yet, but from what I can see of the rest of the porcelain seems to have just a hint and I mean a hint of ever so light brown, so light it almost appears to be green(I know that doesn't make sense, but best way i can describe it)

Here's the best shot of one plug I can get since I don't have my camera here today.

The line on the strap is your timing looks like you have a little more timing can be put in the car.Did ou pull this plug right after a nitrious run?You really need to read whats going on at the base of the porcealin that will tell you if your lean or rich.Porcealin at the base should be clean if its got color your rich

Any running time other then making a full pass with new plugs will not give you a proper plug reading...

No idling.
No cold start up
no driving back to the pits after a pass

the plugs on the dyno are tricky. they will not load it correct.... like above no idle after the run and kill it mid sweep.

Thanks guys. I knew it was kind of useless to try and read these since I did have to drive on them, but I was just wanting an idea. Next trip to the track I'll def. taking the time to read them properly.

Thanks again.
