In 2011, 342,126 voters turned out in Guyana creating an electoral quota per seat in Parliament of 5,263.
In 2001, the highest turnout which was only a handful short of the 1997 turnout, 403,734 voters turned out creating an electoral quota per seat in Parliament of 6,211.
The difference between these two vastly different turnout elections was 948 votes per seat in Parliament.
Assume arguendo that we see a rather strong increase in turnout which is midway between the 2001 turnout and the 2011, you only get a net increase of 474 votes to the electoral quota bringing it to 5,737 voters per seat in Parliament.
In plain English, this only means that the PPP would have to find 474 more voters per seat to hang onto each of it's parliamentary seats plus 1 new MP seat.
I don't think you people have a fundamental understanding of the way the Guyanese electoral system is configured.
