With that system your saying that I can race every week, finish in say 5th place every week but one week 3 random drivers turn up who at some point in a 15 week championship came 4th make me drop down to the lower heats. That then spoils my nights racing and I go home a tad miffed. How has that rewarded my loyalty to the club. At a quick glance at the last championship 40 odd drivers did 11 rounds

but 95 percent of them would have to relinquish their place for a 'random' driver which isn't very fair in my opinion.
No system is perfect including ours and sometimes people will feel they are in the wrong heat but its impossible to please everybody so surely the emphasis should be on the regular club racers.
