Is the Registration Necessary?

Dear all,

I am really wondering how registering to vote while outside of Sudan which lifts up the total percentage of the Southerners while there are no guarantees of actually going to Sudan help voting for secession?
We know that voting for secession will require 60% to be succeeded. If we lift up the total percentage by registering and we don't go, those registrations/votes will be counted lose. For example, if people of the South are 10 million, then the required 60% to win the secession will be 6 million. But if we "people from outside" lift up the total of the Southerners to make them "for example" 15 millions, then the required 60% to win the secession will be 9 millions. If those who registered did go to Sudan to vote, "let us say 3 millions did not go and only 2 millions went", then the calculation will be very hard for the South to get 9 millions out of only 12 millions. Because the total of Southerners in the South will be 10+2 millions.
On the other hand, if we do not register and keep the total of Southerners be only 10 millions "estimated number" then we keep the required number to win the secession only 6 millions. If those who are able to go have actually made it to Sudan, then their number will be still added to vote and we may easily bit the required 6 millions out of 12 millions.
Unless there are somethings I did not know, registering is not good for us.
