I have been reading up on this and have come across both suggestions.
1) Straight in and out to prevent mis-shaped fruit. Also to reduce the number of seeds
2) In straight with a slight twist and remove pinching the petals to ensure pollen makes god contact and stays in
I saw a video that suggested to do what you did. Might I suggest you try both on a few flowers and mark them with a string of different colors. Report back to the forum.
