The difference is because on route convoys merged or ships left and also new escorts were assigned, but I cannot do this in the campaign engine. So Ive put 40 merchants and 8 escorts for now.

HX90 is indeed a good example. According to Hague´s it departed from Halifax on 21 november 1940 and arrived at Liverpool on december 5. It had 8 escorts according to Hagues´s records:
HMCS Assiniboine- DD of C class, escort 21-22/11 (*)
HMS Folkestone - sloop of Folkestone class, escort 02-05/12
HMCS French - auxiliary patrol vessel, escort 21/11(*)
HMS Gentian - corvette Flower class, escort 02-05/12
HMS Laconia - AMC, escort 21/11-02/12
HMS Vanquisher - DD, V&W class, escort 05/12
HMS Viscount - DD, V&W class, escort 01-05/12
HMCS Windflower - corvette Flower class, escort 21/11(*)

Those three ships (*) only escorted the convoy near Halifax. Actually, between 22/11 and 01/12 the only escort available was the AMC Laconia so 5 escorts instead of 8 seems a good compromise IMHO .

Dunno if it´s possible but a suggestion would be to have small hunter killer groups patrolling around the western approaches. Coupled with IRAI´s ability to convoys send distress messages and be reinforced by near warships (within a 30 km radius?) it may be a usefull workaround. Or not .
