No one can answer questions 1 and 3 with any certainty. Regarding question 2, no, not all get the NOI above the cut-off CRS, this is not an ITA.
No one really knows what OINP's criteria for issuing NOI is, whether it's NOC related or not. I guess they pick and choose people that they feel would be able to adjust the best and contribute the most to the state.
At 441, I would think you stand a good chance of getting an NOI, once they start issuing them again. You need to have a profile created after Jan 01, 2018, so you'd probably need to re-create your profile in the EE system. All the best.
