Aren't the suits tested for compliance on the athlete?

I honestly don't see this.

I've looked at quite a few videos now, comparing the techniques between other jumpers and their medal winning jump.

It looks close enough to me and, honestly, plenty of experts, too, otherwise they would have pointed to the difference in techniques enabled by the altered suits, rather than only having to rely on finding alterations after taking the suit apart.
