@ManishDwiv 1. Of course, more lots better the chances.
2. Even on higher lots, better to apply in multiple of 5 lots. 5, 10, 15, 20, 25... There are more applications with these numbers - more applications, more allotees.These numbers mostly always qualify for the lottery.
3. Between 9 and 10 is an interesting choice. Of course for 10, allocation ratio is slightly better but not much. Few people ( I think Jain community) assume 9 is auspicious for them, so the trend I'm seeing there are more applications with 9 lots, because of that more allottees. So if I'm applying only 1 application, i might opt for 10. But if I'm applying more (5-6 applications), I believe better to apply 9 lots as there will be more allottees.
Just my thought process.
