Is there any rule in the phrase "一点也/都不..." when you should use 都 instead of 也 or can you simply use them interchangeably?
As a native speaker, they seem no difference to me.
You can simply use them interchangeably when you want to say "xxx not at all".
e.g.
我一点都不记得。
我一点也不记得。
I don't remember at all.

1The only difference might be colloquial vs. literary. In Cantonese, 都 is more colloquial than 也. It may be different in Mandarin. For example, 我一啲印象都冇(colloquial Cantonese); 我一點印象也沒有(Standard Written Chinese/ Mandarin) – Tang Ho♦ Apr 23 at 22:59
