Yes, ALT1 and ALT2 are just two additional "NORM" settings whose parameters
can be set to what the user prefers for each mode.

Well, I and a lot of the field testers felt the same way.  Even though I
don't use PRESETs I and II for the reason you state, there are some who
really like them.  The use model is different.  It allows you to set up two
temporary filters settings and be able to quickly toggle between them while
operating.  But, for most of us, this is like a "scratchpad" filter memory
because we will never trust that they stay on any particular value since all
they do is remember what the filter settings were when you EXIT that PRESET.
