Minor nitpick: I think you meant to write "<command> | sudo tee". And a question on the comment - In general (I don't have a lot of benchmarking experience, I did a few of them and used lower quartile to reduce the impact from interference), is it hard to determine that the minimum is not shrinking anymore ? I suppose we could run a benchmark until we have a certain amount (say 3, but it will depend on the distribution) of relatively close minimum values ? This seems to be a good way to have a good probability of obtaining the "true time required" you mentioned.
