9 months ago also have 3 user categories so (firewood charcoal), (firewood charcoal LPG) (LPG charcoal) and having these shares add up to 100% then within those you could have the cooking times so that firewood +charcoal=2hrs of cooking time firewood charcoal LPG=2hrs of cooking time charcoal LPG =2hrs of cooking time
instead of calibrating by rural urban calibrate by classes of stoves
Instead of using stove shares constraint(stove shares must add up to 100%) we could use: the cooking time, so that time a summation of the time spent on each stove should add up to total time spent on cooking per day.
