My understanding is, he wants to cook the best BIR food that he can, and possibly better his favourite restaurant. To do that, he needs to understand the science.

It's not really a question of trying to create the 'best' dishes I can, because 'best' is a relative term. I think it's in any cooks nature to produce the tastiest and most enjoyable dishes with the ingredients they have at hand. In that sense I'm no different to anyone else here, they all want to produce the 'best' they can as well.
What I'm trying to do is define and understand each separate BIR curry cooking technique used to achieve the flavours you generically find in most if not all BIR style restaurant dishes. Once all those techniques are defined and understood, you should then be able to not only cook the variations found in most BIR restaurants, ie Bhuna, Vindaloo, Dopiaza, Madras etc, by varying the ingredients but do so reliably and with repeatable consistent results and not the 'hit and miss' results many people here seem to experience.
Once that's been achieved with reliable consistency, you can then transport those skills and techniques to other ingredients and actually start to create new and different dishes from scratch and without following an established recipe.
The big problem I feel for many people here, is that because they simply do not know or fully understand all the techniques involved they're wedded to established recipes and can't move away from them with any reliability.
I'll give you an example of precisely what I'm talking about. You go with a bunch of mates to a new Curry Restaurant you've never been to before, you have a dish recommended by the chef as a 'Restaurant Special' let's say 'Sindhi Style Lamb'. You recognise familiar flavours and you know the principal ingredients, how are you going to replicate this dish at home without a specific recipe, unless you fully understand all the standard BIR style cooking techniques?
That's what I'm trying to achieve.
