It all makes sense to me now, starting in Bohol, there would be only 6 left during that time, here's how it could possibly go down, if there were twelve legs this could be the list, plus the fact that they are cost cutting
leg 7 - Bohol would be an elimination, 6 teams down to 5
leg 8 - Iloilo would be NEL
leg 9 - Misamis is an possible elimination leg with 5 teams down to 4
leg 10 -
is possibly NEL still with 4 teams
leg 11 is an elimination leg with 4 teams down to final 3
leg 12 They can already have the final three racing to the finish line
It makes total sense
