sales forecast patterns

[CasualDabbler]

I'm trying to calculate a number of sales forecast patterns.
Limited snapshot below (Full sheet attached for reference)
There are 127 possible patterns
There are a batch of known average daily profile percentages. I need to forecast what the unknown patterns would look like based on trends from known patters
i.e.
_T_T_S_ (Tue, Thu, Sat) is Typically 36%, 29%, 35%
_T_TF__ (Tue, Thu, Fri) is unknown.
