Punctuation with : ; ,

I am taking a transcription course, but I disagree with some of the answer key's punctuation. We are not to add or take away any words.

This is the unedited version: So we're also seeing that by moving over to the other side of the fence by forgiving by accepting by having compassion we actually see a change in the brain where we move into an alpha brainwave state

This is my answer: So we're also seeing that, by moving over to the other side of the fence: by forgiving, by accepting; by having compassion, we actually see a change in the brain where we move into an alpha brainwave state.

This is the answer key: So we're also seeing that, by moving over to the other side of the fence, by forgiving, by
accepting, by having compassion, we actually see a change in the brain where we move into
an alpha brainwave state.

How would you write it?

Do you have any references on rules? I haven't found an internet source regarding this.

My main question is:
When listing 3+ objects, incomplete phrases, or clauses in a row, but excluding the "and" or "or" in order to properly join the last clause, is it proper to indicate that with a semi-colon?

Thanks in advance!
