Presumably, each copy of you would also want to be part of a copy group, so if the year of pickaxe trench-digging seems to be a good idea at the end of it, your copy will presumably be willing to also put in a year.
Now we get to the question of whether you can choose the time of when the copy is made. You’d probably want a copy from before the year of trenching.
If you have to make copies of your current moment, then one of you would experience two consecutive years of trenching.
The good news is that the number of you doubles each year, so each of you only has to do 4 or 5 years to get a group of 12.
