 SKIP 1                 \ Our current roll rate
                        \
                        \ This value is shown in the dashboard's RL indicator,
                        \ and determines the rate at which we are rolling
                        \
                        \ The value ranges from 1 to 255 with 128 as the centre
                        \ point, so 1 means roll is decreasing at the maximum
                        \ rate, 128 means roll is not changing, and 255 means
                        \ roll is increasing at the maximum rate
