"Standard Spin Recovery" no such thing.
Firstly is it a "standard" recovery checklist, or a checklist used recover from a "Standard" spin (whatever that is!)
Flat, inverted and Knife edge spins all require different actions, and so by definition their can be no "Standard checklist"
Mueller and Cassidy have well described emergency vital actions, that are the only procedures that come to a complete cover all.
Each type also has its own specific attributes, power on during recovery will make the recovery quicker, Aileron input can stop the spin alone, etc etc.
Knowing "Standard spin recovery" is not a green light to spin any type. Each type will have a specific set of actions.
