Yup true. If they continue the alternate pnp/ece and all program draws, high chance score will drop <470 in couple of months. And congratulation on your ITAYup, only thing I worry for people awaiting for ITA is that there will be am inflow of people with PNP nominations, as it seems that in the last few months couple thousand of EOI were given.
Hopefully the majority of those go on the PNP specific draws, helping reducing the CRS cut-off for the general draw.
