on other recipes i struggle say madras. what i don't know is if these challenge the base more or i just don't have a good enough "close enough" recipe. i think it's the later.

This is a really good observation, I think that dishes such as Korma,CTM, Dhansak, Patia, Jalfrezi are far easier to reproduce because they all have other overriding tastes, Coconut,Cream,Lentils, peppers and so on.
However the humble Madras now that's a different beast and boy I wish i could reproduce this.
Just my personal ramblings for what its worth.
