By the way, about local rules in Russia - you must report at the first contact with Tower "request line up" that means "ready for departure" for the rest of the world, and YOU must report "ready for take off", that means you are ready for roll. You can tell Tower both things togeather, if no reasons for delay by you for more than 1 minut, if after clearence for take off 1 minut elapsed you must receive another clearence.
But it is only rule, and you know how we like to follow them in Russia.
