[Elecraft] KPA-1500 Efficiency

[charles at k5ua.com]

Just curious what other users of the KPA-1500 see as the efficiency 
reported by the KPA-1500 utility app.

The following efficiencies are being report by my KPA-1500 utility app 
by band into a dummy load running 40 watts input and 1500 watts output:

80M CW:   61%
80M SSB:  64%
40M CW:   54%
40M SSB:  59%
20M CW:   52%
20M SSB:  52%
17M CW:   55%
15M CW:   64%
15M SSB:  62%
12M CW:   68%
10M CW:   56%
10M SSB:  58%

Does this compare favorably with other KPA-1500 owners?
