I've done it myself with no drama. Yes, 100% focus is required while you are winding up each spring - one slip and it can be a lot of not good. You put rod in, loosen locknut, turn quarter turn, tighten locknut, move rod to next hole, repeat. It's a slow, steady process for each spring.
Springs should be tightened such that the door balances at the half-way open point.
As stated above, the hardest task is getting an accurate weight of the door.
Another tip: there is no one 'right' spring. You can use a range of springs - the longer springs (which cost a bit more) will last longer as they aren't as stressed per each up-down cycle. Builder-grade is the shortest spring that will work. I went a bit longer than original when I replaced mine. Yes, the wire diameter does change a bit with increasing length as well.
I also spray-painted a much brighter white stripe across each spring before installation so one can easily count how many turns are on the spring.
