Well here is a thing.

Sounds like a type II.

I've never hear of a type "pretty big fecker" (PBF)

What type of SN was it classified as????

Type Ibc according to the Nature paper.

Sounds like a type II.

How many types are there and how does a type II rate?

I guess it's all down to density. The denser the star the bigger the boom boom.

What type of SN was it classified as????

Type Ibc according to the Nature paper.

Ib or Ic ? (not that there's much difference).

PJ - A type I does not typically exhibit any hydrogen in emission spectra, whereas type II show strong hydrogen emission lines.

Depends what you mean by rate

There are two main types I and II. Basically if it contains Hydrogen lines then its type II, otherwise its type I. The further subdivisions (Ia, Ib etc.) are based on other elements in the spectrum and also what the light profile over time is.
