Crosswind landing numbers are all about directional control.  Typically you will be trying to find out two numbers, steady state and gust.  The big items for this test are: conditions, environment, pilot skill, planning, and and test point method.  What this means is you have to have a  wide and long enough runway, no obsticals around you, weather that will meet your test points, and the skill to properly fly the test points while staying within you control limitations.  This is a time consuming order, which is why you don't see much data.

I have demonstrated 31kt steady state 90 degree crosswind landing in a Legacy at 2075 pounds landing weight with 20 degrees of flaps and power at idle.  I was able to maintain directional control with the rudder until enough weight on wheels allowed the airplane to track down the runway.  Durring the test the nose gear was within 2 ft of the centerline.  The airplane slide on the mains while maintaining a crab.  Once the skidding subsided as airspeed decreased the airplane went into a predictable track.  The highest I have tested a slip style landing is with 18 Kts. steady state wind.  I think I could get a few more knots but have not had the data point to check this.  At 18kts I was able to achieve runway track with the rudder and it was not fully deflected.  This landing was made at 1870 pounds landing weight at flaps 20 and power at idle.

I hope you find this data useful.  Sorry I don't have the test cg listed in these notes.
