Replying to Speeding up progression

So I'm leaving in a few days for my first tracks this year.

Unfortunately, my season is only 10 days straight like every year.

So NS, how can I speed up learning new tricks? I can slide basic rails like tubes pretty confidently, and do shitty pencil 3s. Started trying blind 2s off last year, but never really got close.

As my time is limited, what should I try to learn? Should I just try to polish up what I can do? Or just try new stuff?

And what should I try if I do what to do new stuff?

And any advise on how to progress faster, and safer would be much appreciated. Cheers
