rate limit for hotspot

I have Mikrotik routerOS v4.13. If I want to create user profile with 64k/512k speed.
In user profile, is it better to spessify the rate limit as 64k/512k or it is more stable to have something like
64k/512k 96k/1M 32k/300k 8/8 8 16k/64k

I want to give the user 512kbps speed but when only browsing and not download I want to give him higher speed for few seconds.

I think, you can mark packets, that is using TCP 80, then set queue tree for those packets limited by more high bandwidth. But you know, that TCP 80 is mass usage of internet usage. I don`t think you can economy your total bandwidth using it. Sorry my bad english.

I don’t know what you are talking about. I am taking about the rate limt in hotspot user profile .

Is it better to set it as 64k/512k or 64k/512k 96k/1M 32k/300k 8/8 8 16k/64k?
