If you accept the statement that most of savate fighters outside France are actually kickboxing WAKO fighters in the first plan or better - In the first line they are kickboxers belonging to other SPORT than savate...
... then you can speculate that most of these people KNOW EACH OTHER from kickboxing WAKO tournaments.
Do you think that STARTING LISTS on FIS "small" combat World and European championships are part of this problem?
ARE ALSO RESULTS AND FINAL MATCHES IN SAVATE PLANNED AND TACTICALLY PREPARED?
WHEN number of competitors is smaller and categories with only few maybe even 3 fighters per category, then THIS PROCESS OF PLANING IS A VERY EASY THING TO DO.
IF YOU COUNT ALSO JUDGES FROM SPECIFIC NATION COUNTRY IN THIS GAME, THEN VISIBILITY IN THESE MOODY WATERS BECOMES BETTER.
If somembody in this game called "SAVATE tournament" decides that he doesn't love specific management team of some specific national Savate federation and wants to change them with more suitable group, then he will try to contact his target group separately (without intervention of National savate federation) and make everything to arrange RESULTS in advance.
It is not very difficult job. Just few phone calls and you have it.
In this way kickboxers have calculated and sure SAVATE results every year in another discipline called savate - which brings them additional money for their other kickboxing activities.
And if somewhere in the world - new and fresh savate team appears (which wants to train especially and only SAVATE) - THIS DIRTY TACTICS WILL CERTAINLY KILL IT IN A YEAR OR TWO. Or turn it into kickboxing group with the same behavior - hiding real kickboxing activity behind one or two savate tournaments per year.
WE TALK ABOUT IMAGINARY SAVATE FEDERATIONS WHICH ACTUALLY DON'T EXIST.
The old tactique of ITF taekwondo - fighters - when they competed in one of 3 ITF federations and later also in kickboxing WAKO (WKA or IAKSA) light contact was, that they took one or both results from very similar disciplines.
If they didn't succeeded in the first they made it in other discipline.
So you were always the winner. And important thing for the development of fighting sport is that you promote yourself as a world/european/regional champion.
Most importnat role in this story are subventions. Yes MONEY. You are right.
In smaller newly created post war countries (Serbia, Croatia...) it was not difficult to get subventions for savate from almost fresh Ministries of Sport or recognition from very Young Olympic Committees.
