I will often estimate 3x as a rule of thumb. Estimating is indeed difficult especially when dealing with unforeseen task switching.

I was surprised to not see “story points” mentioned in the context of scrum. This is an estimation concept I have found baffling because it is a measure of “complexity”, not time, yet is used directly to estimate how much can be done. At least this is how it is done at my work.

Scrum lingo is silly.
