I don't suppose that'd be the case. But still there are some variances to those advertised specs. Afterall, all the DC readings I got are still almost within - 5 percent of the advertised specs. (8.50K * 0.05 = 0.42K

)
PG+, by the way, is a PG with an a5 mag, wound a little hotter. They come stock on fender lone star strats, or sold in Fender boxes. But still they are manufactured by Duncan. Do a search, you'd find lotsa info on them.
