Here's my tips.
If the time bonus of 5000 is possible, consider collecting as many rings as you can within the 1-min time period, unless you can get a really humongous ring collection. Otherwise, simply go for collecting as many rings as you can without screwing up a lot. Remember, each ring is 10 points to your score, while each second (when you're not within a 1 min. period) also costs 10 points. Follow this and you should be off pretty good.
Also, SAing in SADX is also part luck because of the random ring amounts in the random ring containers. This is why even when I could do perfect, the amount of rings in the ring containers screw me over.
That's the basics. Other than that, simply rely on your SADX skills and you should be off fine.
