It it really is a piece of cake. If you can’t make the time at this point, you advise ATC and they give you vectors. Or you drop to a lower level and slow up. Green dot is a knot higher for every 1000 feet over 20. So you can get some good speed reductions down low. Especially east bound out of the jet.
Anyway, stick with it son.
What’s wrong with flying at green dot in any Airbus (turbulence excepted)? It’s not going to drop out of the sky. In fact even at VLS it’s not going to drop out of the sky.
Just let the automatics do their job, and then when it can’t, intervene
