Change small salvage to 3 mins

[vapid heron]

every other salvage has the 3 min average duration according to the wiki, not sure if this would change the meta for sailing early on, but feels rather odd that the small salvage is the one you have to be most active on to get the clog (maybe add a different small salvage spot to a mid/high tier sea with a better duration timer)

[final sentinel]

small salvage has a "triple spot" south of lands end near Auburnvales shoreline, this makes it the best AFK salvage spot in the game because there is always an active spot.

[gritty pasture]

yeah for 2-3k an hour. terrible clog
