I have a table of data. In column A, I have the names of tasks and in column
B I have their expected finish dates. I need to find only those tasks that
have the sub-string "Execute Assembly Test" (approx 107 tasks) and then
determine, based on column B (expected finish), the date that we can expect
90% of those tasks to be complete. Can anyone help me, I'd like to attempt
to do this in an efficient a way a possible.

Thanks again.

***I would prefer to not have to paste data into a new column and then do
calculations of those values, but I'm not certain there's any other way.
