interesting to compare this number to number of 4DM made. I
wouldn't want
to fly one myself.

It would appear that 100 Nimbus 4D were built, of those 11 were 4DT
and 12 were 4D leaving a total of 87 DM of all types.

There is a list of 7 accidents in the previous post due to loss of control.

Just over 8% of the total built have been lost to loss of control
accidents.

I wonder how many other people have to die or parachute to safety
before someone asks the question, should this glider be flying at all.

As the N4DM is certified, it had to be demonstrated that it will exit a spin after 3 turn at most.
Loosing 1800 m in any certified glider while trying to stop the spin is hilarious. This corresponds to something like 12-15 turns. Something has gone wrong very seriously.
