Besides, if you are slowly rising above PD and order PD again they in fact try to reach periscope depth again but you won't recognise much of a difference because of your slow speed your positive bouyancy will be stronger.

If you order a greater depth in the first place (the 16 or 17m perhaps) then your boat will rise to ~14m. So order this depth when just diving and your speed is still high enough to press the boat deeper.
When you are already at 2kn or less you will be too slow to sink deeper and would have to speed up again first.

mfg, i.

Precicsley, just order your boat deeper!
