An “amount” is something not measured in units, although it CAN be, and when referring to the units you would use the word “number”. For instance, you would refer to an “amount of water” or a “number of cups of water”.
Therefore, you have an excessive *number of threads bumped today, not an “amount of threads”.
It CAN be, meaning it CAN be measured in units if you were to rephrase the sentence . I put that in so you wouldn’t say “well, water IS measured in units, I used 4 cups of water to make soup”.
If you are not using units in the sentence, don’t use the word “amount”.
