So I think I've got my suspension set up for sag, and the typical compression and rebound settings   

She is still hard as nails when it comes to bumpy b roads. I recognise that the bike was built for silky smooth race tracks, but as I rarely take her on a track, is there much I can do to make the suspension a bit more forgiving on more normal routes? I'm about 80kg in gear and on the stock online springs.

THe only thing you can do is reduce the damping, then if still too stiff get softer springs, if you have the ohlins set up springs are readily available....

If you have the forks pinched together it can cause excessive stiffness, and if the swing arm and linkage has seized or rusty can cause choppy damping, replace the bearings and it will ride softer....

According to Maxton. Here is a copy of an email document from them
FORKS
The forks on the Mille feel very notchy and harsh and kick off small bumps,
this is because they have too much compression damping over small
movements, however when you brake very hard you can feel the forks
bottom out, this is because the springs in the forks are too soft, the other
problem is that when you let go of the brake the forks spring back at you
and the bike does not turn into the corner as well as it should, this is
because there is not enough rebound damping, we increase the rebound
damping and we fit harder springs to suit your rider weight and also to suit
what type of riding you do. We also revalve the cartridges of the forks
increasing the rebound damping to control the forks extension. Many
people complain about the lack of feed back or feel front the front end,
the conversion cures this problem and stops the front feeling vague.
The fork conversion costs £380.00 plus worn parts i.e. Seals - £25.00 and
Bushes -£25.00.
A service on the forks would cost £120.00 plus worn parts.
ALL PRICES EXCLUDE V.A.T.
REAR
The rear unit is a Sachs unit as appose to the Showa front forks and is a
unit which we can service but cannot buy any parts for. The spring on the
unit is approximately about the right rate for the average weight of rider,
the biggest problem with the unit is there is not enough travel in it, the
standard unit only has 25mm of shock travel which means that after 70
mm of wheel travel (about 3 inches) the shock will bottom out on thebump stop, causing the bike to launch you out of the seat. You will make
the problem worse if you load the bike up with a pillion or luggage.
Unfortunately there is nothing we can do to change the design of the unit
which means we cannot stop this problem. We supply a Maxton
replacement unit which is a fully adjustable, alloy bodied, high pressure
gas unit that adjusts via shim stack system. The unit has a ride height
adjuster and a spring to suit your rider weight and to suit what type of
riding you do. The NR4 unit costs £435.00 but we also make an RT10 piggy
back remote reservoir unit that has a second compression adjuster which
costs £605.00. ALL PRICES EXCLUDE V.A.T.
The later bike has a different linkage which works at a better linkage ratio.
The later linkage has a softer ratio meaning you need a softer spring to
get the same feel at the back of the bike. This gives the shock a much
easier time.

It's easy to have the forks not parralel , ie the forks tighter at the wheel and wider at the top , this causes friction and wear.

Although you might not have the same forks as the rsv4 the fitting is the same. You want the brakes and the forks sitting correctly...

There's other youtube videos, also lighter oil can reduce the bumps....

That relates to the Showa set up on the standard bike if I'm not mistaken,the R's Ohlins is more dialled in as standard I think

They're spot on with their assessment of the Showas though
