My 2 cents worth as an amateur and very chicken.
The knowns about a IVP.
1.  My IVP stalls at 71kts.  (There is a very distinct buffet and
straight ahead stall with the stall strips.)
2.  1.3 times stall is 92 kts and is the minimal safe maneuvering speed.
3.  Stall speed increases with weight.
4.  Stalls are to be avoided at all times. 5.  This is not a STOL airplane.

Therefore the plane is on the ground at 90 kts.  Departures:  Rotate nose wheel off at 90 and let it fly off at 90-100
kts even more.  I don't care.  Don't force it, it will come off when it
is ready.  Approaches are the same:  downwind at 120, base at 110 and final 100.
On the ground at 90.  Leave the flaps on for drag as it won't lift off.
Apply the speed brakes.

One story:  4000 foot strip. Hot, clear summer day.  I accelerate to
about 90 kts when a dust devil appears on the runway 300 feet ahead.  (A
dust devil is a miniature tornado--cyclonic air usually picking up all
the dust and trash with wind speeds of maybe 30 mph.)  I have never
encountered one on takeoff or landing before.  I can't begin to stop.  I
keep on the power and pin the IVP on the ground until through the dust
devil.  The IVP wiggles and dances some going through.  We launch at
120kts on the other side.  It was a non event.  If I had lifted off and
was accelerating in ground effect, I suspect the result would have been
very different.  My mind set is that when there is a possibility of wind shear,
turbulence, any air disruption at all, I am much better off being a
little to hot than not having enough control by being a little to slow.
