No.

I think you went the wrong direction. More like Zone I 2/3 (that's why I said place shadows on Zone II - close enough).

But, come to think about it. Now if I did use a lower EI... And I still place my Shadow on Zone II - It's like I really placed my shadows on Zone III.

Gets messy real fast.

Fortunately that isn't a "bad" exposure.
