Good point os, great extension lumps' post.
Feel what the aeroplane is doing. I.e The arrow IV will begin to attempt to bounce the nose wheel approaching 60 knots (arrow 3's do it also, but not so pronounced). A little back pressure cures it. great op to do a rescan of your eng instruments and asi. by the time you get through that she's pretty much ready to fly.
Adding 10 knots? hmm IIRC the old CASA chart for something like the 210 also has a TOSS line. If you can find one, do one with any given set of numbers, and then add 10 knots to the TOSS and work backwards a bit. You will be surprised at the effect.

Don't get me started on the old Casa charts
A few have had a crack at me because I liked them. Most of the Yankee manufacturers charts rely on you using 'rules of thumb' for things like different surfaces.
So wheres this list of 'rules of thumb' we are now supposed to use
Worst change i have seen! (other than juliar)
