I think you got it wrong. By the number of 'chances', it doesn't mean the x no. of queue numbers will be generated. Rather, you will have four times the opportunity to get ONE queue number. Its like having four applications at one go.

Balloting is just the nicer way of naming lucky draw because it works the same. The more slips you have inside the lucky draw box, the higher the chance you will get picked. And of course if you are lucky, one slip will kana already lor, but then the next thing is whether you kana first prize or last prize lah...

I think this is fair because if we want to argue who deserve or who need to get the flat more, the reasons are endless and can argue until the cows come home.

Ballot is suppose to be fairest provided it is open to all applicants..like Pri Sch registration..but HDB ballot was never open, so how to define fair in this case ? I see some applicants easily get a flat while other try for many times, never get a good number

I balloted for over 2 years before I got my current unit. It is a painful experience. FYI
