Optimal Number of Bullet Points in Copy (Are odd numbers better than even numbers?)

When displaying bullet points in text or in a slide, is there an optimal number of bullet points?

I remember some marketer telling me odd numbers 3 or 5 are better digested but can't find any information regarding/supporting this. Are 2 or 4 points just as valid as 3 and 5?

3 and 5 points do look better for me, anecdotally.
