Interesting timings, Stu.
I cook my tikka-marinated half chicken breasts over a standard Weber kettle BBQ and I give them 4 minutes before turning them and giving them another 4 mins. Actually, those timings are just the same as when I cooked them under the cooker grill in times past. The only difference is that the meat was right up at the flame under the grill, whereas the meat is probably 6 inches or so above the coals.
I didn't consider that the tandoor method might take longer, but it just goes to show that there's more than one way to achieve the same outcome.
As long as it tastes good - that's all that matters to me. Vive la difference !
