Tony,
I have added the results for 9V:
10V???9V?
Band?PWR-W?I-mA?PWR-W?I-mA
160??6.55??1150? 5.19?1047
80???5.35?? 928??4.24? 851
60???4.99?? 925?3.92? 859
40???5.73?? 975?4.49? 898
30???5.68??1363?4.45?1256
20???4.86?? 931?3.89? 872
17???3.57??1258?2.95?1189
15???5.73??1613?4.86?1532
12???3.89??1553?3.45?1486
10???5.05??1282?3.97?1182
6????3.87??1080?3.61?1068
Regarding lack of sufficient drive, I don't think that is the case here.
DL4JAL has designed a CW only 5W transceiver, which uses the same set up as the classic
'Sierra' using band modules to change bands:

The power amplifier is inspired by the QMX+, but he uses Mitsubishi medium power fets with
bias power control instead of BS170's and claims 5W out on all bands.
