Besides SCRM, is there any other focus effects/aa/buffs that extends the duration of SotW beyond 30 seconds?

I know of Focus of Mediocrity, prolly a few more too.

If Focus of Mediocrity is able to extend past SCRM.

I am not talking about caps now, just how does the skill round.

5 ticks with a 50% duration boost is 7.5ticks, which rounds to 8 ticks (I have seen 8 pulses though someone told me they saw the points fall back a bit so /shrug).

But...

5 ticks with 65 duration increase (SCRM plus 15% for mediocrity) is 8.25 ticks.

7.5 rounds up...but does 8.25 round DOWN?

Or, is there no rounding but partial ticks...in which case mediocrity would gain you 3/4 of a tick over SCRM?

Just dunno.

Extended Enhancement does, so I don't see why not. I first bought SCRM for Nature's Recovery, because I could combine it with Extended Enhancement III and usually get either exactly 5 minutes (66.67%) or 1 tick shy of 5 minutes (63.33%).

As to the rounding question, I suspect (but am not sure, since I haven't tested in ages) that it works like Torpor -- the full duration with buff enhancements depends on the moment you start the spell. If you start it late enough in the current tick, you can get the extra duration.

The other focus effects that should affect it are:
Chrononostrum (+25%, beneficial only, min duration 4 ticks)
Eterninostrum (+20%, beneficial only, min duration 4 ticks)

I think these effects are only on drops from elemental gods and above.

does SCRM stack with shawl 8 in increaseing SotW?
heck - does shawl 8 by itself extend SotW?

Shawl 8 only works with buffs > 45 seconds, so it does not work with SotW. From what I hear (don't have so this is second hand info), shawl 8 does not extend with SCRM which would mean it checks off the base and not the extended.
