I use a simple excel document (open office calc document actually, but it's the same thing).
Format the document so the "Total" column is the sum of the rounds. Highlight, copy, and paste it directly into a thread and you can update it from within the thread by clicking on the box you want to change.
Like this:
|
Round 1 |
Round 2 |
Round 3 |
Round 4 |
Total |
| Player A |
65 |
65 |

|
195 |
| Player B |
65 |

|
|
130 |
| Player C |
65 |
|
|

| Player D |

| Player E |

| Player F |

| Player G |
