Several units had changes made to them for 2.1 that may affect
sinking/damage.
Not sure which units are in the training stuff as that's to tough for me.
You will get different results depending on the rise and fall of a unit in the sea.
As a ship riases, zones may be open to hits.
As it sinks, those zones are covered again by the sea and take less damage if any.
Any tests I do?
I run at lest 75 tests.
Most times I run 100 tests.
I also must hit 15 perfect test in a row before I'm happy.
