I would agree. Its all about what you are trying to achieve, and whether this brings you closer, or further away. For me, it was closer.
Regarding the "slowboat" technique, I question this for many of the same reasons why I asked why the chilli is added later to the liquid base. The single biggest breakthrough for me in BIR cookery (other than use of a base) was the importance of spice frying. Kinda flies against the slowboat technique, not that that cannot produce a great result - I admit I have not tried it.
If the new technique specified "add the spices after the second lot of base", then I would compare it with the slowboat. I need to do some more experimenting. The biggest problem with experimentation is doing so when you are already getting good results...
