Where are all the engineers/ math experts that can explain the tech pros/cons of 3 and 4 cyl 1620 ccm turbos!

Imho i dont see any advantage.If you could explain will be usefull.

Well as an example, 1000cm^3 two cylinder motorcycle engines tend to produce more torque earlier in the rev range than 1000cm^3 four cylinder. Given the restrictor formula "forces" engines to be "low reving engines with lots of torque down low" there is a similarity in the power delivery i'd say, if the displacement per cylinder really does make a difference under current rules is another matter.

Inside Toyota's Insanely Powerful 3-Cylinder

[Fast Eddie WRC]

The Fiesta ST switched to a 3-cylinder 1.5 engine with the Mk8 and it makes more power than the old 1.6. It's also used in the Fiesta Rally3 so it's clearly been found to be a good configuration.

Or... they had to use it for homologation purposes...

I remember they said something about 1.5 instead 1.0 at Rally3.

Nikolay Gryazin just took the new Fabia's second victory at Rallye Hirvenal du Devoluy. He won all but one stage, Loubet was his closest rival but he retired after 7 stages with mechanical issues. Tricky to read too much into it because of conditions/tyre choices etc but the winning margins on some stages were quite large. From the videos i saw Gryazin looked pretty comfortable with the car already despite just one day testing. Results here:
