[Starlink] Optimized for Speedtest?

[Daniel AJ Sokolov]

Hello,

 From this list I have learned that Starlink is optimized to shine in 
tests with speedtest.net and similar sites, but that transmission rates 
drop quickly after about 15 seconds.

How do they do that, technically?

Is that a result of Bufferbloat? Is that a a specific code in the modem 
to cheat, like some car manufacturers cheated on emissions tests? Is 
that something done in the satellites who shift capacity from other 
users to those users who initiate downloads? Is that done on the backhaul?

Thank you
Daniel
