This request is similar to another of mine, but is about another topic. The similarities are that they abide by the same rules and the formula should be applied in the same system. In the following the only difference will be the 3rd column of the table, from my previous request; it may seem trivial, but it's not. Oh! And I removed a paragraph about a meta matter (in which forum to post the request). I have a mostly automated profile/sheet/information that I'd like to automate even more as it allow custom formulas using limited data and operations. In the following table, the column (col) 1 is entered (by the profile/sheet/information) then col 2 is automated and I'd like to do so for col 3; currently col 3 is entered and the user is supposed to verify it's correct when col 1 is changed, but it's more than negligibly forgotten so the user doesn't benefit from having a col 3 as high as possible (using the table constraints). If possible, I'd end up with a custom formula to generate col 3, the only information it could have is col 1 & 2 and the only available operations are arithmetic (+, , x & /) and rounding (round(), floor() & ceil()). There is no need to figure col 2, it's only there if it helps finding the formula for col 3 (with the restrictions of the previous sentence). I haven't figured out how to enter a table in this forum (BB code for table doesn't seem to work). The following is a TSV, which I imported into a spreadsheet then printed to the attached PDF. Code: 1 2 6 2 2 6 3 2 6 4 2 6 5 3 8 6 3 8 7 3 8 8 3 8 9 4 8 10 4 10 11 4 10 12 4 10 13 5 10 14 5 10 15 5 12 16 5 12 17 6 12 18 6 12 19 6 12 20 6 12 Thank you kindly for your help.

Except for the 20th row, the third column in row n is now 2floor(n/5) + 6. Are you sure you gave all the values in the third column correctly?

The third column contains "8" and "10" exactly five times, but "12" occurs 6 times. What's the pattern?

If you had difficulty understanding the list in my last post, for its points the # in "Bardic Inspiration (d[#])" are col 3. (I was going to edit it (my last post) and mention the update here but can't do so.)

The formula 2floor(n/5)  2floor(n/20) + 6 will produce 12 for n = 20. Will you ever need a 21st row?
