I don't think the drying is taking to long. my thoughts would be that 700 bft of RO would take me 30-35 days to dry to 7%
The fact is your charge is 30% larger than normal and RO dosen't like to give up it's bound water very easily. When you start to dry you are removing all the free water first, that usually dosen't go to bad but getting the bound water gets tougher.So to me you have about 6-7 days left of drying and as I said earlier the last few % of MC slows done to about 1/2% per day for me anyway. You are at 10% and 1/2% per day is another 6 days witch will be about 32 days which seems right on the money for me anyway.
You are still pulling water which is good, but I think your cooling coil temp may be reaching it's peak. At 110f with 10-11MC your RH should be around 60-65% which gives you a dew point of about 85f. or so and I think your cooling coil is probley around that. I don't know if you can check the coil temp but that would be important to me so you know where you stand as DHing goes. If your cooling coil temp is very close to the dew point as the RH drops you will see things really slow down.
If you have vented in the past and had success I would stick with it, if you look at the pics of my kiln you can see some flaps on the ends and front of the kiln. Before I put on the A/C unit that's all I did was vent.
That's my take on this

PS are we the only ones on this post I am sure there has to be someone out there that may have a better take on this than just me
I don't have a good enough knowledge on the science of drying just what I have experienced in doing it. Maybe somebody out there has a handle on the science end of it and can add something
