I am writing a technical report. After finishing the first draft, I asked my friends, who are native English speakers, to proofread my writing. They found and corrected several errors in my report. For example, my original writing was:
The bound scales with the aperture size, coherence width, spatial spread, and signal strength.
One guy corrected it like this:
The bound scales with the aperture size, the coherence width, the spatial spread, and the signal strength.
On the other hand, another friend corrected it as
The bound scales with the aperture size, with the coherence width, with the spatial spread, and with the signal strength.
To me, both look OK. But, I am not sure which one is better. Problems related to repeating or omitting articles and prepositions in a series of items always confuse me.
