Sum multiple TIME()'s

Question

I have this table of scores:

---------
| TIME  | 
---------
| L4:10 |
| W2:32 |
| L2:23 |
| L6:10 |
| W1:10 |
---------

To convert a score to an actual time, I use:

=TIME(0, MID(A1, 2, 1), MID(A1, 4, 2))  [ which outputs 00:04:10 for the A1 ] 

Is there any way to sum all these totals at once without creating new cells?

(Note: I cannot remove the L's and W's from the original cells)

Answer 1

Consider wrapping it up into ARRAYFORMULA this way:

=ARRAYFORMULA(SUM(TIME(0, MID(A1:A5, 2, 1), MID(A1:A5, 4, 2))))

This will sum all the values in A1:A5 range into one cell.

Answer 2

Very slightly shorter:

=ArrayFormula(sum(1*regexreplace(A1:A5,"L|W","00:")))

Returns 00:16:25 when formatted accordingly.
