Equip a slow speed sub, I'll be using a UWSy'Sy' for 5 speed
First up, find base > destination time
The Isle of Sacrament, look at top line only
Time to Destination is around (8610 minutes / your speed).
Multiply this number by your speed to get time to destination, around 8610 (looking at a 70 speed sub, will have it more accurate with a 5 speed)
Do the same for all zones, and this gets your the first column of the table. A->B is the same as B->A, so you can transpose values and fill in the first row. Here's a sea of ash time table as reference:
Next column starts with A -> A, this is where I put in my survey timeCode:(H) A B C D E (H) 0 11184 14300 16864 16163 25322 A 11184 B 14300 C 16864 D 16163 E 25322
This value will be around (61,600 minutes / your speed)
Multiply this value by your speed, to get around 61,600 minutes
Select The Isle of Sacrament as a destination, then record the time from there to the other zones the same way you did Home -> each destination, that's your 2nd column, which you can transpose as your 2nd row as well
Remove The Isle of Sacrament as a destination and select the next zone as your first stop, and record it the way you recorded The Isle of Sacrament. The number of recordings gets smaller each time, because you have already done the zones above you and can skip them.Code:(H) A B C D E (H) 0 11184 14300 16864 16163 25322 A 11184 33600 6640 7193 10381 23265 B 14300 6640 C 16864 7193 D 16163 10381 E 25322 23265
When you get done you have something like this:
To find total time for a voyage from the chart, here's a C -> B voyage as an exampleCode:(H) A B C D E (H) 0 11184 14300 16864 16163 25322 A 11184 33600 6640 7193 10381 23265 B 14300 6640 33600 11956 15494 12416 C 16864 7193 11956 37800 10601 24547 D 16163 10381 15494 10601 37800 14033 E 25322 23265 12416 24547 14033 42000
(H) -> C
-6864 to travel from base to C
C -> C
-37800 to survey C
C -> B
-11956 to travel from C to B
B -> B
-33600 to survey B
(return to base is not figured into equations)
Total is 100220, divide this by your speed, let's go with 70
1432 minutes
23 hours, 52 minutes
Add 12 hours for prep and return to base time (or whatever reason you feel like, it's how the game is programmed to figure it out)
1 day, 11 hours, 52 minutes
I'll map them all out on Tuesday, after my subs finish their current voyages
