Right, sorry. Conflating two different parameters there.
However, 15 Mbps peak + 2 sec GOP could be a compelling option for trying to get long-form content on DVD-5/6 media where the ABR is low enough that PBR isn't going to make it that high anyway, and you're more worried about overall efficiency.
