[Elecraft] K3: Sherwood Receiver Test Data question

[Dick via Elecraft]

Please advise if I am reading the new Sherwood receiver data  correctly:
 
1) it shows a nice 6-8dB  improvement in 3rd order dynamic range after 
adding the new  synthesizer? 
 
2) it shows that the K3's sensitivity  has been greatly reduced from the 
original 0.33 & 0.19 to 0.8  & 0.5  after the addition of the new synthesizer? 
 If this is  true, this would be bad news for weak signal 6 & 10-m.  
reception.
