timesaving
/tīm′sā″vĭng/
adjective
- that saves time, especially by using a shorter route or a more efficient method
- prompt or expeditious
In this context, it would be more fitting to use "time savings." Here's a revised version:
Routing A: Time savings of 30 minutes with a probability of 50 percent.
This wording is appropriate because "time savings" is used as a noun phrase to describe the amount of time that is saved. It's expressed in the plural form to indicate a quantity of saved time.
Don't follow your gut as shown here https://www.merriam-webster.com/dictionary/time-saving the correct way to say this sentence is "Time saving of 30 minutes with a probability of 50 percent.
Time saving is singular Time savings is plural in this case it's one time saving, so routing a is the correct answer.
I know there are some words like time-saving, labor-saving, etc., but these are adjectives. I need a noun.
