No matter what you do, the gain factor for each frame will
never be allowed to exceed the frame's
local max. gain factor – the maximum that this particular frame could be amplified
without any clipping (distortion).
Furthermore, the
actual gain factor applied to a frame will usually be even
lower than the "local max. gain factor", because we apply a
minimum filter followed by a
Gaussian smoothing filter to each "neighborhood" (sliding window) of frames.
The "max. gain factor" option is an
additional hard limit on the maximum gain factor that can be applied to frame. This mostly exists to avoid
humongous amplification factors in extremely quiet (almost silent) sections of the file.

This tool, for example, can create a graph of the "loudness" (ITU BS.1770 and CBS) of a given file:
