Grammar Corrections: First, the original sentence needs some help with grammar. In this list (below), the original sentence is first, followed by potential grammar corrections and word variations. Added spaces make comparing sentences easier:
We count the number of techniques used for efficient result. (ORIGINAL)
We count the number of techniques that have efficient results.
We count the number of techniques that produce efficient results.
We count the techniques that have efficient results.
We counted the number of techniques that produced efficient results.
We counted techniques that had efficient results.
There were three techniques that produced efficient results.
We counted each technique that produced an efficient result.
We determined each technique that produced an efficient result.
Realistic Example: For a realistic example, suppose you have these results:
An "Efficient Result" is when Efficiency >= 50%.
Technique Efficiency Efficient
T1 30%
T2 48%
T3 59% *
T4 66% *
T5 91% *
Efficient Techniques = {T3, T4, T5} = 3 techniques.
Given the above results, suppose you needed to include a step in a process manual:
- Step 3 of the process: "Count the number of techniques that have an Efficiency >= 50%"
If you needed to report to management, you might say this in an email:
- There were 3 techniques that had efficient results: T3, T4, and T5.
(Efficiency >= 50%)
