Hi there. I have a column consisting of the following:

S A S S S G S A A S S S S A G A S S A S

I need to track the aphabet "S" if it appears =2 times. The column cell is
updated weekly. In the above sequence of the column (left to right), "S"
appeared 3 times first then 4 times again after the break in sequence. [see
bracket e.g. S A (S S S) G S A A (S S S S) A G A S S A S]

The formula for the cell to track and sum up should base on the condition
that if "S" =2 then start counting until break in sequence. If it appears 3
times first, then a break, then 4 times again in sequence - the formula cell
should register the latest sequence count (i.e. 4 times). Is this possible?
