I've been "playing" for a year & a quarter & I found my fingering to be wanting when I looked at the theory
But I was quite comfortable with my fingering.
What I did try to do was to test my fingering against the fast runs going back & forth to see if there was anything flawed with it.
Where I found my fingering wanting, I adapted it to the recommended, otherwise, stick to the most comfortable fingering for a specific key.
