Thanks for sharing that SD.
I was never a HUGE fan of really hot curries, but Chewy's Madras is among my favourites that I cook up. It's always a challenge for me, but so addictive, i keep going back for more. ( I must be toughening up.HA!)
We had an Anzac DayBBQ at a friends place yesterday. he asked me to bring a couple of curries down for yet more people to try.....and guess what? Chewys Madras was the most popular. The intersting thing was that there were a few Aussies there too. This is the first time that an Australian (born and bred) has tried my curries, and they were seriously impressed.
I've said it before, and I'll say it again. THANK YOU people for sharing this knowledge. 
Hi Mick,
I have to admit that in the past 5 or so years my chili tolerance has depleted somewhat and I now opt for a milder curry. However, (for me personally) I believe that it's the taste in the curry and not necessarily the heat that needs to "define" a dish.
Nowadays, as opposed to years gone by, when you ordered a Madras, it came out from the Kitchen as a standard, and you had that dish, no matter how hot it was and you ate it.
In today's Indian restaurants, when ordering, a lot of waiters ask you, "How hot would you like that?"
So, I believe that a Madras and other dishes can be produced for their individual taste and adjust the heat level to suit the individual...
Whereas, anything above a Madras, i.e. a Vindaloo/Phal/Berkshire Fire Eater clearly has a label stamped on it and is for the asbestos stomach's amongst us in this forum and elsewhere!! ;D ;D
