Title should be 7,207 frames per sec.

I'd guess that most people intelligent enough to discuss the localisation of thousands separators are also intelligent enough to infer the difference between 7.207 frames per second and 7,207 frames per second when applied to the photography of lightning strikes.
So I think we should extend the original poster the benefit of the doubt and assume that they just wrote the title in their native tongue without a second thought rather than maliciously intending to deceive us all.
No one think they were trying to deceive, but it's possible they were trying to provoke commenters or appear worldly. Still, most likely explanation is just a mistake.
