Oops I apparantly looked at outdated docs (on scenergy):

That documentation is not really complete. The supported settings are:
* FIXED, DEFAULT, NORMAL: the default behaviour, and behaves as
described in the docs.
* 1, 2, 4: the set size depends on both the low and high value of the
set element type (e.g., a set of 16..23 will be 1 byte in case of
{$packset 1}), with
a) the lower bound rounded down to a multiple of the packset setting
expressed in bits
b) the upper bound rounded up to 'a multiple of the packset setting
(in bits)' minus 1 (e.g., 24 is a multiple of 8 bits in the above
example -> -1 = 23)
c) if the set size would be 3 bytes after the above calculation, it's
changed to 4 bytes
d) if the set size would be greater than 4 bytes after the above
calculation, it's changed to 32 bytes.
* {$packset 8} is also supported, but kind of nonsensical in the
current implementation (will always be rounded up to 32 byte, since
the set size will always be > 4).
