I understood the NRL had reduced 5-day turnarounds to very few last year?
Anyway, to fully bust the myth - Broncos turnarounds this year were:
2 nine day turnarounds
3 eight day turnarounds
7 seven day turnaround
7 six day turnarounds
1 five day turnaround
Looks like a fairly common thread across other clubs. Roosters for example:
1 eleven day turnaround (post-anzac day)
2 nine day turn arounds
2 eight day turnarounds
4 seven day turnarounds
12 six day turnarounds
0 five day turnarounds
Basically it looks like most clubs get around five longer breaks (eight days or more), 14-15 six or seven dayers, and in Brisbane's case, they even had one five-day turnaround. It's not an exact science and some clubs will fall outside it, but it seems common enough.
In previous years there's no doubt Brisbane benefited from being constantly Thu/Fri nights but there's no doubt that changed a fair bit last (this) year.
