[O.B.Left]

Yes, I'm afraid it is. The only throwout that's not throwaway is #3 Throwout.

The non auto left wrist throw can be early or late. If you watch Lynns video above where he demonstrates the plane of the left wrist cock you will hear him suggest that vertical left wrist motion (uncorking) makes horiZontal left wrist motion (bending, throwWay, loss of rhythm ) less likely. He puts it in a more resolute manner actually , something like " the good news is you can't do this while you're doing this" . Sorry on my phone and going from memory.

For sure you could do it early too early . But the hackers over the top problem that leads to throwaway is not the same deal.

Sequenced Release by definition will throw out #2 first.
