I don't think you're gonna get much better than that as far as accuracy, TSO'd AS indicators limits generally range from 2 at the low end to 7 mph error at the upper end.
If you were to ask me I'd say that's pretty darn good at 2-3kts error, most analog instruments are double that.
And is a few knots really that important?
As far as the altimeter matching your transponders output that's meaningless from an accuracy standpoint.
