I have been using an iPad Pro with forScore for some years now. If I buy new sheet music I soon convert it. Only recently have I realised that there are additional benefits for the ageing guitarist. I have been converting my scores from standard portrait pages to zoomed landscape pages. Reading scores is so much easier now!

I believe this is a common experience. As Blaise says, it is similar to anxiety in public performance settings. And as she says, repeting the behaviour frequently usually results in the anxiety becoming less. Indeed it can be used as a step in combatting public perfomance anxiety. And the results of the behaviour need be shared with no-one else unless that is what you wish.
