Much to my regret, I don't. However, I kept it very simple. I took 1-2cm blobs of burr comb on my hive tool, and just pressed and smeared sideways gently onto the frame faces at about 10cm intervals. You don't need to cover the whole frame, just put enough on to make it smell like the hive. Each frame face ended up with about 12 blobs of smushed wax pressed into it. The bees cleaned it all up within a day or two.
Sorry to have created extra work for you. I agree, if they can talk you through their method and it works in your area, fine. However, just remember that you only have 8 frames in a Classic Flow hive, so their bees have 25% more space in the single 10-frame brood box for storing food. I am not saying it can't be done, just it might be tricky balancing the feeding. I would love to hear how it goes after your first winter. I know that a lot of crazy Brits overwinter on a single brood box too, but their box sizes are different again.
