Care to quantify that BB? 
Most members on the site, from what I've heard, would say that although they can produce fairly similar curries to a BIR, still feel that they are their efforts are lacking, compared to those of a good BIR. However, using any one of the set of our more successful base recipes, most will produce curries of similarly good results.
We still have some way to go to getting it just right. Our best efforts at the base seem to plateau at a certain level, with several recipes producing very very similar end results. The result is very good, although still lacking that missing element.
We have not made much progress with this since I have become a member, with factors like economy and availability of ingredients weighing into member's judgment into the likelihood of a new ingredient's feasibility and as such many suggestions are disqualified and or written off. In the past year, I don't think that the general consensus has changed.
Having said that, I'm sure a newbie would be pretty happy with SnS's, Darthphal's, Ifindforu's or Bruce Chapman's curry base.
Assuming a new member knows one pan from the other, has the correct ingredients and a set of scales, and eats BIR fairly often, I really don't think it takes Gordon Ramsay to follow the instructions. A few attempts should iron out any obvious flaws.
I think our man has done a sterling first attempt of the Bhuna from looking at the pictures and I'm glad that he's happy with his results.
