CSP Power Tower Molten Salt - Solar Receiver Queries

Dear Paul & Michael:

A few questions on the SR behavior observed running the default plant configuration on SAM 2022.11.21, it would be great to have your feedback on them.
1. Reported “SR Inc Power” does not match (always lower) the value obtained using “SF Inc Power” * “SF Efficiency” * “SF Focus Fraction” in cases where the SR is absorbing power for the start-up process. Why?
2. Reported “SR Efficiency” does not match the value obtained using (“SR Inc Power” – “SR Conv & Emission Losses” – “SR Inc Power Start-Up”) / (“SR Inc Power”) in cases where the SR is actually absorbing power for generation and absorbing power for the start-up process. Why?
3. Reported “SR Mass Flow” does not match the value obtained using (“SR Inc Power” – “SR Conv & Emission Losses”) * HTF Cp @ (“HTF Inlet Temp” + “HTF Outlet Temp”)/2) * (“HTF Outlet Temp” - “HTF Inlet Temp”) in general. The discrepancy is important in cases where the SR is actually absorbing power for generation and absorbing power for the start-up process. Why?

Thanks.

Javier Pastoriza.
