fat dog , all good apart from the dive dont use speed brake advice.context tailwind, cu, atc level offs.va et al
surfing a wave gets you there faster doesnt peneterate the wave.
tailwind and increase of speed equals the above.
The vnav physics/logic to slow up when high is sound.
the wing is sh1t (or too good depending on your life philosophy),cant achieve it
speed brake makes up the difference, diving just gets u to the scene of excess altitude sooner.
head wind context then i'll dive , dive ,dive with the saltiest 3x hghtplus ten dinosaurs./
just follow the pink one and level at the green one and you'll be cool
