Well @firebombmarkus - the big difference is if you use any boosters. I see you have 21 +1 and 5 Hunter the dog boosters available - which can make a huge difference if you decide to use any of them (or the single tractor or the shovels). Without boosters I would guess close to what @Chicken_Slayer said but if you use some boosters - well then its almost anybody's guess. I will guess 157,000.
