Would you kindly consider ... that the transit times of troop convoys (& therefore, naval movement in general) to the Middle East is currently inequitable.

Viz.
If I despatch a troop convoy from Cardiff to Port Said via the Mediterranean, it will take 7GT to arrive.
If I despatch a troop convoy from Cardiff to Port Said via the African Cape, it will take 6GT to arrive.
IIRC, the Mediterranean route was deemed to be the fastest but potentially dangerous if contested, whilst the Cape route was deemed to be the slowest but the safest route.

Whilst the advisory information upon entering the transportation loop does state that the estimated time to arrive is 1GT, I have never actually observed this taking any longer at all. This may beg the question: what are the inbuilt % chances (if any) of it taking 2GT to exit the transportation loop?
Nevertheless, regardless of whether there is any chance of the voyage being delayed by a GT, it is still far too fast even allowing for game playability fudging. Pure mileage would suggest that overall, such a sea voyage should take x3 the duration of the direct Mediterranean route. Gamers would almost certainly never use the transportation route at all if the voyage from Cardiff it would require c.21GT to arrive!
Whilst being fully cognisant that all of the naval movement is primarily based upon the relative speeds of the ship types, rather than their true distance capabilities, the duration required for movement via the Cape transportation loop should simply be longer relative to the time required for the more direct Mediterranean route.
I would respectfully suggest that the minimum time (or base time if any variation is desirable) that a troop convoy (or other naval fleet) should be off map via this transportation loop (to the Persian Gulf or Red Sea), is approximately 4GT. This would make the overall voyage time c.50% longer than taking the direct route via the Mediterranean and recreate the reality of the faster/dangerous vs. slower/safer route choice dynamic.
Additionally, if a random element of uncertainty regarding the transit time of long haul routes is deemed desirable (& the less perfect the information for the players, the better, IMHO), perhaps a simple (or variations upon a theme): 50% chance of arriving on time; 50% chance of arriving 1GT later than the ETA. Applying this to the specific route in question would result in a troop convoy arriving 10-11GT after departing Cardiff: surely a step in the right direction?

What think you?
Kind regards.
