We did it as a shared google doc. We'll either figure a way to share that with everyone or I'll make an excel doc with it. But then you can put in any amount for added non-BFL. And you can put in your order number and see a graph for you.
I was chatting with some other ppl today who said that BFL's first batch was 21TH. But honestly that would only cover about 700 x 25GH units. By that measure, they'll be sending one of these "batches" every day or two.
I thought I had heard that BLF-Josh said that anyone who had ordered in the last two weeks would get theirs by July. But now I can't find that quote again.
I did find this on their website:

PPS, It maybe best to go with 50% cancel & 2 units/order. That will make this shipping "guess" closer to both 30 & 70% because half way in-between them. This would make sense since the actual cancelled orders are unknown by us and could be somewhere between 30-70%.
33,000 * .5 * 2 = 33,000 units / 2,000 = 16.5 weeks = 4.125 months + delivery time.
This falls more in line with the guessing that we did.
I'm going to write them and ask some direct questions. Note that this was a while ago. They're up to order number 40000 now and I doubt that the 1000 orders a day they're getting now includes ANY cancellations.
