I think what kraksy means is. if you entered twice in top 150 the your chance is increased but very small and that increase other chance to, even player who entered top 150 once. so no matter how many you got to top 150, your chance is still the same with someone who entered top 150 once.
let's just say:
kraksy and mafioso has entered top 150 once, and zach never entered before. after the 11th DT there are total of 1650 players who entered the lotteries for getting in the top 150. so kraksy's and mafioso's chance is 5/1650.
in the 12th DT, there are another 150 new players(outside of 1650 above) that entered top 150. and lets just say kraksy at 151th, mafioso didn't played, and zach at 150th. if the rank is stay the same until DT ends, their chance is 5/1800. kraksy got his 150th and zach down to the 151th, then kraksy's chance is super slightly increase from 5/1800(0.002777 to 5/1799 (0.0027793) and so mafioso too even he just entered the top 150 once. but zach of course didn't have any chance.
to put it more simple,
there are 50 players who determined to get the cr's and played 12 DT and got all 12 DT into top 150, so if other players entered top 150 once each player then there are 1250(100*12+50) total players in the lotteries. chance is 5/1250 (0.004)
but if there are 100 got all day top 150 in each DT and other players just once each, then total players who entered the lotteries is 700(50*12+100) players. it's 5/700 (0.007143) chance.
the chances depends on the total players that entered top 150 a day, but all the players have equal chances.
the lesser the total players the bigger the chances is. when someone entered twice, it's N(total)-1, 5 times then N-4.
ya, instead of saying "your chances does not increase" let's just say "you not only increase your chance but you increase other players (top 150) as well)
