based on the above tables (assuming you attempt upgrades everytime possible) on average it will take: to get

lvl2 5.6mins

lvl3 60 mins

lvl4 200 mins

lvl5 750 mins

lvl6 800 mins

lvl7 1050 mins

lvl8 2250 mins

lvl9-13 4500 mins each

for a total of 27615 mins to get 1 lvl13 part (which will naturally be higher since youd want to be using it) again yet another way to give free players a little taste (while reserving the higher lvls to pay to win players)
