So I think that the time it takes to rank up should increase by 15% each rank b 30,000 c 34,500 d 39,675 e 45,626 f 52,470 g 60,340 h 69,391 i 79,800 j 91,770 k 10,5536 l 121,366 m 139,571 n 160,507 o 184,583 p 212,271 q 244,111 r 280,728 s 322,837 t 371,263 u 426,953 v 490,996 w 564,645 x 649,342 y 746,743 z 858,755 Each next rank sells items for more money, so now we gotta apply the amplifiers. b 30,000 c 34,500x2 = 69,000 d 39,675x3 = 119,025 e 45,626x4 = 182,504 f 52,470x5 = 262,350 g 60,340x6 = 362,040 h 69,391x7 = 485,737 i 79,800x8 = 638,400 j 91,770x9 = 825,930 k 105,536x10 = 1,055,360 l 121,366x11 = 1,335,026 m 139,571x12 = 1,674,852 n 160,507x13 = 2,086,591 o 184,583x14 = 2,584,162 p 212,271x15 = 3,184,065 q 244,111x16 = 3,905,776 r 280,728x17 = 4,772,376 s 322,837x18 = 5,811,066 t 371,263x19 = 7,053,997 u 426,953x20 = 8,539,060 v 490,996x21 = 10,310,916 w 564,645x22 = 12,422,190 x 649,342x23 = 14,934,866 y 746,743x24 = 17,921,832 z 858,755x25 = 21,468,875 so I guess those prices are going to be the rank up prices. Don't get intimidated because, for example if you were rank y trying to get to rank z, everything you sell would be 25x more. Rank a sells 1 coal for $1. Rank y sells 1 coal for $25 dollars. So the true number is 858,755. That is still a massive number and I think it is like 15 hours of work. Anyway I'm just writing this for my self. I just did the math just now in this post and now ill go punch these numbers into the bulksell multipliers and the rankup plugin. Thanks for reading.
