737 Perf. inflight Actual LDG distance

[In dis-sky's]

Hi all, a quick question regarding the 737 Performance inflight Actual LDG distance table:

The table lists corrections for 'No reverser' and '1 reverser'.
Now I understand why this is the case with MAX MANUAL braking, but why does it list corrections for different autobrake settings as the autobrakes provide a decelleration RATE. ie they apply less brake pressure when you use reverse thrust.

Thanks
