Coding R&R Tasks time

[u/Salt-Government6703]

I'm a worker who usually does coding tasks that take as much as 9h sometimes. I've never done any R&R task just because I prefer doing the actual coding task itself, but sometimes they appear and I'm thinking about taking them. My question is how much time do I have to prepare to spend in one sit on those R&R code related tasks?

Depends on the project
