You're right. It is unfair that glow will be getting lighter and higher performance as the flight goes on. And the electric will be losing power as the battery discharges. Any ideas on how we can get the glow to weigh the same throughout the flight? Oh, wait a minute, maybe a power-to-weight graph throughout the flight will converge and then it will show the glow will be better at the end of the flight.

Lots of ways to massage data.
