True.

No need to go for WolframAlpha, either. Just look at the LOS:

3J9*3-2-1-5-4-3-7-1-9...

To extract the number of repetitions of all the arrows (or the PGN array, which is basically the same thing), just subtract 1 from all the numbers:

2-1-0-4-3-2-6-0-8

So you're right. It's 6 G's (three-arrows).

(I probably absent-mindedly added 1 to the 7 in the LOS insteaded of subtracting 1).
