When does the bonus round finally arrive?
Deciding to chase the bonus round means accepting that it arrives at an unknown rate. No one can tell in advance how often the Free Spins trigger in Lady Wolf Moon MEGAWAYS™, and the result of one session is random whatever the RTP says. The RTP describes the long run across very many spins, not the next hour.
Deciding which RTP version to rely on starts with the game rules, since the version running in the Axe Casino lobby is shown only there. Read that section before the first spin, then compare it with the versions table on this page.
Deciding how big a session could get means treating the maximum win as a ceiling, not a target. Lady Wolf Moon MEGAWAYS™ stops a round once the total win reaches the multiple shown in the table, and a win at that ceiling is reached very rarely.
