Your analysis is problematic because you have fit a linear trend to 4 samples to make a projection. The point on your graph from the 2015 year-end report is a serious outlier that affects the magnitude of the trend, which by the way does not have any confidence interval. Also, you don't account for the quota admissions from the various streams or the number of ITAs issued to-date.GOOD NEWS! The score will definitely go below 400 soon!
Here is why:
- I have been doing a lot of calculations using the last three stats released about the number of candidates in the pool and their scores
- Felt like it was not sufficient data for predicting the trend over the next rounds
- I found out that they released the same data about the pool as of 3/Jan/2017 in their Year-End Report 2016
- I used that to predict the next few rounds, given the average number of candidates added per day over the last 4 months
- The results [taking into account the changes they introduce mid June]:
- Conservative estimate: CRS goes under 400 on July 26
- Regular estimate: CRS goes under 400 on July 5 (Likely Scenario)
- Optimistic estimate: CRS goes under 400 on June 21
- You can see the trend in the pool since January here:
This makes it really clear!
