I believe the rules indicate that even in your own port there is natural attrition of the mines 5 to 10% per day (i.e., they float away into the great blue abyss). In the open ocean I believe the rate is as high as 50% per day.
The attrition is 1% off a base or dot (friendly or not), 5% off a land mass without a base and 50% in open sea.
As for building MLE building 3 seem too much for me for both sides at start. I only convert one at start (available in spring) and then 1 or 2 in spring-summer 42 (available in fall). Two AR are far more useful IMOO than two MLE.
That depends on your mine philosophy I guess. I lay a lot of mines with my subs, and I use the MLEs to reload them. The Jap short range subs cant stay on station very long, so I use them for mine boats. US subs arent terribly effective until late '43, so I use them as mine boats as well. I score more damage with mines from US subs in 42 than I ever did with torps, and Im not risking the boat doing it.
Edit: And I think (not going to dig out the rules and look it up right now) that the 1% decay is only at friendly bases, and 5% at other (including enemy bases) coastal hexes. This would account for the mines actually being tended to (which they were) at a friendly base, and not being tended to in other locals.
