I find the factoring hours thing a bit of a joke to be honest it just degrades you even more. Im currently a first officer at a different company but I fall under the cadet category when appling for Wizz.
1000 factored hours is about 1300 total time at 0.8, im not sure if wizz are doing this as a buffer.
This is due to the different SOP's at different companies. Someone with 1000 hours at Wizz will be more fluent in their operation than someone with 1000 from airline "B". Same applies at EZY.
