I've been getting over 96% reduction in block-bytes sent. I don't have a good metric for it, but bandwidth spikes are greatly reduced. The largest blocktxn message I've seen on a node that has been up for at least a day is 475736 bytes. 94% of the blocks less than 100kb must be sent in total. In the opportunistic mode my measurements are showing 73% of blocks transferred with 0.5 RTT even without prediction, 87% if up to 4 additional transactions are predicted, and 91% for 30 transactions (my rough estimate for the 10k maximum prediction suggested in the BIP.
