Well the only thing you can take from that is that you never managed to get over the critical angle of attack.
There is a exercise to which you should have done which is recover from an incipient stall in the landing configuration which is set up as you say then pitch up gradually maintaining a shallow decent until the stall warner goes of and then recover from there. Its not mean to be a fully developed stall or have a constant airspeed. It meant to simulate you pitching up on approach without adding power because you are low and not noticing your airspeed is decreasing.
The other one is a turn with partial configuration and again recover with the stall warner.
Its not the best idea of intentionally trying to get a fully developed stall in a steep turn, you can quite easily manage to stall one wing and not the other and get thrown over the top in either direction into a fully developed spin in a mode which may never have been looked at in the certification flight tests and may not be recoverable using the POH technique.
