You can set up this trick during the two and a half minutes of waiting during the mission. What you have to do is memorize the package locations, pick up the mission, then get to the docks ASAP, set up the replay while going as fast as possible with the boat, then drive back to Donald's place, and activate the replay after the final package had dropped already. I have not tested whether it's possible to make all of this happen in time, but it should be.

You can NOT pick up the same package multiple times.

I tested this for a while, here are the results:

• You can get back to Donald's place if you have a sportscar from Waka Gashira, including going to the Ammu Nation and getting the banshee at the docks.
• The weather in the replay can be different to what the weather was when you recorded the replay. If the weather changes to calm to storm, the boat in the replay will take a rather different route because of it, causing you to miss the packages.
• The strat could save about 35s, see karl's comment below.
• I have not attempted to find reference points for the packages.

I believe this is not worth the time save unless someone can find a good replay route and the weather issue proves to not be that much of a problem. Would be cool in segmented runs, though.

This is pretty fantastic I must say, done right this will save a lot of time, around a minute if I'm right?

• The strat could save about 15-20s if done perfectly. Since it only saves the drive back to Donald's place, minus the replay length. And the drive is pretty short.

Edit: it's about 35s faster, check karlskomment

http://www.twitch.tv/karlk/c/6952057 Police boat is better for this and is fast enough if you skip ammunation.

New adito is about 35 sec faster than WR and can be done a couple of seconds faster still. Comparison:

Tutorial for this.

nice tutorial, with reference points and everything i noticed there wasn't a fixed banshee near asuka, is that normal ? I'm wondering if getting a banshee there is worth it, my guess is yes because you should have a few seconds to spare as long as you don't crash like you did on that video

That banshee always despawns if you don't get into it before going to sea. Maybe taking it before would be faster, has to be timed.
