Hi John,
I don't know why the numbers are there. But since they are part of a comment, they have no effect. Maybe these are the stock values (3 and 4 seconds) so that one has a reference
One word of caution: Finding the correct hex value is not always easy and since S3D adds a comment to the beginning of a file, hex offsets are often different between stock and modified files! I recommend to have a test file with all probabilities equal 100% and then activate the 'no-launch' option in SH3 Commander. This allows you to quickly test your work by opening the modified file with S3D (after SH3 Commander has modified it) and check whether the value has indeed been changed. Using this method I have found quite a few wrong hex offsets...
Best, LGN1
