I think they likely to be quite different. My last post estimated that roughly 2% of XMR coins were mined before the public miner was un-de-optimzied. What is corresponding percentage of BBR coins? Since the emission curve is reasonable I still don't think the number is that large (compared to absurdly instamined coins -- and shills for these coins on this thread you know who you are) but it still may be higher than XMR. Or perhaps not. I haven't really been following it so I don't know.
