Did your instructor teach you slow flight? Slowing down and hanging out some

allowable airspeed is taught.

Slow flight would have been good had there been time. I was abeam the
end of the runway when cleared to follow the Arrow. I was in B airspace
(so it seems) around 20 seconds later.

BTW, the provision in the 7110.65 requiring controllers to coordinate
airspace transits applies to controllers who are providing radar services.
Somehow, I don't think that the BFI controller was providing radar services.

BFI has radar and is separating me from other traffic, right? That is
not technically "radar service"?
