Is tris a loophole? Is it used by other teams? Could be just a trick of perspective of course
It is a trick of perspective, probably caused by carbon fiber orientation and by the radius between the two perpendicular planes, not reflecting light, that goes down to 0 while approaching the diffuser.
Basically: Reference plane and Step plane must be linked by
one (and only one)
vertical surface; two radii are allowed to join the so formed perpendicular planes.
Relevant articles:
3.12.3 The surface lying on the reference plane must be joined around its periphery to the surfaces
lying on the step plane by a vertical transition. If there is no surface visible on the step plane
vertically above any point around the periphery of the reference plane, this transition is not
necessary.
3.12.4 The boundaries of the surfaces lying on the reference and step planes may be curved upwards
with maximum radii of 25mm and 50mm respectively. Where the vertical transition meets the
surfaces on the step plane a radius, no greater than 25mm, is permitted.
A radius in this context will be considered as an arc applied perpendicular to the boundary and
tangential to both surfaces.
The surface lying on the reference plane, the surfaces lying on the step plane, the vertical
transitions between them and any surfaces rearward of the surfaces lying on the reference or
step planes, must first be fully defined before any radius can be applied or the skid block
fitted. Any radius applied is still considered part of the relevant surface.
