Hi Alex,
That sounds like an impressive turn around to be honest, it’s not easy to be able to change tactics dramatically in matches and under pressure and it’s very good to be adaptable like that and not just one dimensional! You’ve mentioned here a few parts on the serve and return which shows how key that area of the game really is and results can often hinge on how well you perform in these areas.
This is also why video recording matches can be very useful as you can look back on them and learn from what went wrong or right and improve tactics and other areas in the future. Hope you are keeping well at the moment!
Tom
