I totally understand your concern honestly. But I have both good news and bad news
There are a few tricks yea, but other than that I don't believe wiki rates are possible unless using tick perfect + modifying the client (e.g. runelite), I've never seen anyone reach those rates for longer than 5 minutes. And even if you come close to those, you're just risking your account banned. You'll have to turn off all random behaviours/antibans and possibly use a combination of things listed below.
But if you wanna speed it up, use these tricks:
- Barbarian vial smash
- Stamina potions
- Esc closes bank toggled on
- Mouse invokes enabled (stealth client)
- Action-bank open toggled on
- Set withdraw/deposit X to All
- Low ping world
- Turn off automatic GE restocking
- Turn off login/logout breaks
