Re-eneactors focusing too much attention on the principate?

Do we really have enough data about ring size to draw any chronological conclusions? (Serious question!)

Mmm, don't know if we've enough data for this, but on the top of my head I think to remember I've read some statements of this somewhere. Have to dig through my readings of last year, though to find out which comments it were and where they were based on.
