Right so if July 2017 ICT NOIs have been carried out in this year's 25% allocation, there might be also a chance that they might carry out the excess NOIs this year in the next year's allocation because of the high demand with ICT workers.
Also, take in to consideration the trend on the previous draws this year vs last year, there were a lot of people who were sitting in the range you mentioned last year than in 2018. Also, if there are really a lot of people who is on the range you mentioned, why would OINP be issuing targeted NOIs to francophones and those with job offers with CRS as low as 351? Anyway, for your reference-

On the other hand, I am not saying that OINP will again re-issue targeted NOIs this year to ICT NOCs with CRS below 400 (Which I hope they do) based on the facts stated above. Maybe they're just re-calibrating their processes as of the moment that's why they paused for a while.
