Since you're mentioning OVH, it reminds me of a story I've been told about Octave Klaba, OVH's founder (not sure if it's true or not actually): he is said to have forbidden any meeting "longer than 90 minutes" in his company. By "longer than 90 minutes", he means that the total time spent by the people participating in the meeting should not be longer that 90 minutes (so 2 participants -> 45 minutes, 3 participants -> 30 minutes, etc.). This fits your logic perfectly.
