case study(hypothetical) : Mr x is in a pool with crs 434, Mr y is in the pool with crs 437, Mr z is in the pool with crs 442, Mr B is in the pool with 425 ..oinp sends noi to all 4 of them. Mr z neither accepts or rejects the noi... He has hopes for the crs to come down to his level in a few federal draws.... Mr y is in the dilemma what to do so he decides to wait out the 45 days validity period of noi and then decide... Mr x and Mr B immediately grabs the noi and make their application after paying 1500cad...now oinp takes more than 3 months for processing.. In the mean time the crs in federal draw drops to 434 and Mr x gets a direct Ita... Now Mr x is again in the dilemma what to do.. So he thinks to hell with pnp il go with direct ita since till then his pnp file is moving with a snails pace (since getting a noi, making an application and paying 1500cad do not always gaurantee pnp nominations) and he starts with his direct ita application which seems more easier and less time consuming then pnp... So now oinp has got 1500cad and one more used noi to reuse.... As for Mr b, before crs touches to 425 he gets his pnp nominations which he accepts and proceeds further in a normal course... So if we assume that there r 50 numbers of Mr x in the pool with his kind of situation then oinp will have 1500*50 cad in their kitty plus 50 nois to resuse.... Smart very smart what say...
