From the car company "Chevrolet" website........
However, from today, help is literally at hand as scientists have created a mathematical formula for the perfect handshake taking into account the twelve primary measures needed to convey respect and trust to the recipient......
The mathematical formula has been developed for car brand Chevrolet as part of a handshake training guide for its staff to prepare them ahead of the launch of the new 5 Year Promise offer, which aims to offer peace of mind and reassurance to its customers........
PH = √ (e2 + ve2)(d2) + (cg + dr)2 + π{(4<s>2)(4<p>2)}2 + (vi + t + te)2 + {(4<c>2 )(4<du>2)}2
(e) is eye contact (1=none; 5=direct) 5
(ve) is verbal greeting (1=totally inappropriate; 5=totally appropriate) 5
(d) is Duchenne smile - smiling in eyes and mouth, plus symmetry on both sides of face, and slower offset (1=totally non-Duchenne smile (false smile) 5=totally Duchenne) 5
(cg) completeness of grip (1=very incomplete; 5=full) 5
(dr) is dryness of hand (1=damp; 5=dry) 4
(s) is strength (1= weak; 5=strong) 3
(p) is position of hand (1=back towards own body; 5=other person's bodily zone) 3
(vi) is vigour (1=too low/too high; 5=mid) 3
(t) is temperature of hands (1=too cold/too hot; 5=mid) 3
(te) is texture of hands (5=mid; 1=too rough/too smooth) 3
(c) is control (1=low; 5=high) 3
(du) is duration (1= brief; 5=long) 3.

This is the most inappropriate use of mathematics (among other things) I have seen in a while. How hard is it to just give a firm handshake!
I know a first impression is important but this just seems to be over the top, especially since every person is different and a handshake is supposed to be a "personal" thing. Modeling it and then getting staff (in this case car salesmen and women) to train to the model, and then marketing it to the world just reeks to me of insincerity, not personal connection.

What are other peoples views?
