no no no, that shouldn't be an issue.
people have to understand that these points do not, in anyway shape or form depict the actual PR's. If anything, all this point system will do is to AID the panalists when making/updating the PR list, so as we dont have to scavange the boards looking for results and such. Something everyone must keep in mind is that order on the PR list is not determined by who places where how often, persee, but more heavily on who beats who how often.
everything of course is taken into consideration but lacking ability to go to every tourny shouldnt be a problem as far as PR's go, however it would logically affect ur points based on this system.
take it as u will, i wouldn't worry much.
in all honesty i think it'll better everyone if we just stop worrying so much bout pr's with every match, and just take things as they come, tourny by tourny.
