Hoi Ric,

I presume that the 0.041 should be 0.41?
Your central value is larger than what I had obtained when we first
got the CBX, shown in
http://www.slac.stanford.edu/cgi-bin/lwgate/VUB-RECOIL/archives/vub-recoil.200306/Author/article-21.html
At that time the "default" central value was at 0.0213 (vub = 4.70),
for CLEO's parameters I had obtained BRBR = 0.0231 (vub= 4.90).
I think that this is a short-term fix. On a longer time-scale
(summer?), I guess we'll using sl measurements with Neubert's
calculations.
Cheers,
--U.
