It's the same charge.
If you expect a 40gr grain max and reduce it 10%, you're at 36.0gr.
The first three steps are in 2% increments because the assumption is that you don't want to use that low of a charge and you're just proving it safe.
The rest are in increments of 0.7-1.0%, which for 40gr would be 0.28 (rounded to 0.3) or 0.40gr.
All percentages are based on the max charge.
