"ALI lost a few(4?) years in his prime (26yrs old to 30yrs old) out of boxing to then came back and take the title off Foreman after six return bouts"

Sounds confusing, what I meant was when Ali returned to Boxing after 4-5 yrs out, he had 6 bouts against different Boxers before he regained the title, Two were against Frazier, the first was a title shot, he lost, won the second against Frazier then went on to Foreman and won the title back. imo
