Don't know if this was reported before, but there is a problem with the "Total amount of damage needed for next challenge" fields in the "Ascension & Challenge" tab. I noticed it for Gold 5 Ugh Solo, which requires 9.54T CD, but was displayed as 95.4T. The root cause for the problem seems to be numerical inaccuracy due to division of large numbers in the format string. My solution is to simply avoid that division by replacing the formula in F34-N34 with the following:
=IFERROR(if(len(F33)<=3, F33, if(len(F33)<=6, left(F33,3)/10^(6-len(F33))&"k", if(len(F33)<=9, left(F33,3)/10^(9-len(F33))&"M", if(len(F33)<=12, left(F33,3)/10^(12-len(F33))&"B", if(len(F33)<=15, left(F33,3)/10^(15-len(F33))&"T", "Only the Fed knows."))))),0)
=IFERROR(if(len(F33)<=3, F33, if(len(F33)<=6, left(F33,3)/10^(6-len(F33))&"k", if(len(F33)<=9, left(F33,3)/10^(9-len(F33))&"M", if(len(F33)<=12, left(F33,3)/10^(12-len(F33))&"B", if(len(F33)<=15, left(F33,3)/10^(15-len(F33))&"T", "Only the Fed knows."))))),0)
