The discussion is deviating from main topic. But just adding one last reply.
Calculation of rs per miles is very subjective. It varies from person to person depending on how u value it (not the airlines) and how much effort u put in getting discounts in revenue bookings.
When u say u get 0.85 per miles value, did u reduce the taxes paid for award booking and usual 10-12% discount we can get from cards on revenue booking? Or atleast Skyscanner price? Also, did u compare with cheapest revenue option or only with the one airline u wanted to fly via award flight. If anything is no, then in my case, value would have been lower. But in ur case, it may not be.
Even for accor, I don't see it at 1.8rs value. As u get 25-40% discount and Many a times I end up choosing a better hotel than what I would have chosen if I went with revenue option. So, I see only 0.7-0.9rs value on average even with Accor. For example, if I am getting a 2 star hotel at 10K revenue after all discounts. But if Accor has only 5 star hotel at that place which is priced at say 25K points (45K INR), I will see value of just 0.4rs per point. I have actually did a few such bookings with about 0.5rs per point value just to experience the luxury once a while. But it won't be every time.
