~~- sum of PSU(unknown) input watts in addition to DC2DC watts, either on ASIC Stats page or main page, as for estimate of power at wall or PSU efficiency~~ <- will implement in 2.6.7. For sp20 I assume 90% efficiency

I think you misunderstood me:
the low voltage DC2DC watts are way below (80%) the watts at the PCIE connector inputs in SP20. And the efficiency between the PCIE and the wall is determined by the PSU and should be around 90%.

I mean summing up these 4 values underlined:

-----BOARD-0----- PSU[UNKNOWN]: 0->(162w/162w)[162 162 162] (->162w[162 162 162]) (lim=288) 0c 306GH cooling:0/0x0 -----BOARD-1----- PSU[UNKNOWN]: 0->(152w/152w)[152 152 152] (->152w[152 152 152]) (lim=288) 0c 289GH cooling:0/0x0 -----BOARD-2----- PSU[UNKNOWN]: 0->(176w/176w)[176 176 169] (->176w[176 176 169]) (lim=288) 0c 326GH cooling:0/0x0 -----BOARD-3----- PSU[UNKNOWN]: 0->(171w/171w)[171 171 171] (->171w[171 171 171]) (lim=288) 0c 320GH cooling:0/0x0

multiplied by PSU eta they are pretty close to the actual consumption at the wall.

may be also a nice point to watch on next generation miners to optimize that 20% loss of the dc2dc units.
