early august for 7.3.
25th of march for 7.2.
So 5 days of march + april + may + june + July + X days of august, let's just say 10 for an even 4.5 split as is usual.

4.5 months from August would be December+January so basically February early for 7.4. 4.5 from that is June for 5.0.

6.55 was January 16, 6.5 was october (released in two parts). Basically 3.5 months between 6.5 and 6.55. So mid-late september for 8.0?
