[TriEmbed] ATTiny84A internal temp sensor: how good?

The internal sensor in the ATTiny84A stinks without calibration. What I
can't find in the datasheet (section 16.2) is how good it can get with
additional calibration points. Would it be reasonable to expect to make
it accurate to +/- two degrees C across a 0 to 70 degree range if I can
calibrate it across the full range and refine the slope measurement or
is the linearity likely to be too poor?
