@New Kid On The Block It seems you and many have misapprehended proportionate allotment system.Let me give you explication of proportionate allotment.
How come you stated proportionate allotment is lottery? You believe if it gets oversubcribed it's lottery but it is NOT.
Lottery allotment is something when each applicant gets equal weightage for allotment,but in
proportionate allotment 13 lots applicant will always have an upper hand than applicant with less than 13 lots.Example if it gets oversubscribed by 15x,it would be 13/15 chance for him(13 lot applicant) to get an allotment whereas 1 lot applicant would have 1/15 chance for an allotment.There will be individual lottery in sub categories example 13 lots,12 lots ,11 lots...But as I mentioned just before that all higher categories have better chance of allotment so we cannot name it lottery since everyone(applicants with different lots) is not eligible with same ratio.
So as you mentioned only higher lots will get allotment is not true even 1 lot applicant will be eligible for allotment.The chance of the applicant definielty reduces but that what proportionate allotment means.
So it's not harmful to apply x number of lots since the higher the lots you apply higher the chance you get no matter what subscription figure is.
I hope you got something better to learn🙏
