Has anyone else verified these numbers on the latest batches? 56W/th vs 64W/th in high power mode is a pretty giant difference.

Well I just finished a few tests with the A1047 I rcvd on Monday:

Date: Oct. 1, 2019
Miner: Canaan Avalon 1047
Rcvd: Sept. 30, 2019
Power source: Triplite 6kva dual-conversion UPS
Voltage out: 230V +/- 0.5%
Ambient temp: 85F (29.4C)
Note: UPS is also powering a M10 pulling 2.17-2.18kw, this baseline load is subtracted from UPS readings to give test miner load.

- Miner in Normal mode for 30 min -
Power: 2.06kw
GUI speed: 31.31THs
Efficiency: 65.79W/THs
After 24hrs speed/power are the same.

Date: Oct. 2, 2019
- Miner in High Performance mode for 1.5hrs -
Power: 2.65kw
GUI speed: 37.6 THs
Efficiency: 70.48W/THs

Do note that the miner is running in a fairly warm room and that definitely affects power usage.
