Thanks, Jan. The slats are fine. They are linked by a cable and therefore deploy simultaneously. I guess there may be a delay or advance between right and left deployment. I'm usually busy at this stage of the flight so I can't focus in the leading edge devices. If they are deploying at different times, this shouldn't be occurring.
In my feeble mind, if this was the case, the right side would be deploying generating more lift initially.
Thanks for your response.
Best,
