Seasoning with Boveda 84%... What target RH?

[shopkins82]

I got up to 80% corrected on day 8 and it held steady there for all of day 9. Beginning of day 10 I pulled the Boveda to check the seal. It dropped quickly to 70% corrected but has stayed right at 70% for going on 24 hours now. I'm somewhat shocked by this since the humi is one of the cheap Perdomo branded "SureSeal" humis you see on CigarBid all the time. I picked this one up on eBay for $9 shipped. There were some gaps at the miter joints of the inner lid lining lip that worried me so I did go ahead and go over the whole inner lip with painters tape, even though it passed light test and dollar bill test everywhere.

Should I put in my 65% Boveda packets and give it a day to regulate to 65%, or can I put the 65% packets and cigars (already at 65% in Tupperdor with the Boveda packs) in together?

Thanks!
