So according to R1 data, they invite at least 59% of the gmatclub pool? Right now we are at 20% for R2. So is it safe to assume 1/3 of the invites have been sent out?
The one thing I've learned in the past few months: It is never safe to assume anything when it comes to admissions.
That being said, ~60% interview rate is a bit high, but close to some others. Word is applications are up, so perhaps that's lower for R2. In an extreme case I'd say that is ~40% interview invitation rate. Even if you figure a fair number of people on GC got interviews but didn't update their status (say 10% of applicants), then for even a pretty bleak scenario there are still a bunch of invitations waiting to go out. If I had to venture a guess, I would guess that about half of the invites have gone out so far.
At least, that's my convoluted logic on the whole matter.
(Edit: Last year the interview rate was around 70%. That means there are still a number of invites yet to go and the original estimate of 2/3 left to be sent out doesn't seem too unreasonable)
