Additionally manufacurers of Mosfets and Igbts and manufacturers of driver circuits provide those informations as "application notes" and "design guides".

Physics stays the same... and the formulas given in the manufacturers documents usually are true.
But we don't see if you use the correct formula and insert the correct values from the datasheets.
So if you show us yourc alculations we could surely better assist you.
This could speed up for you to get the correct values.
Hi
There are many ways to calculate the required current for gate of a mosfet .
One of them is based on Vc=C(dv/dt) which can be easily used to calculate the ic . ( according to the ciss )
The other way is IG=Qg*F it came from this issue :
C=Q/V and I= Q/T ==== > C=Q*V
