Bronnen & referenties
Onze benchmarks zijn momenteel gebaseerd op branchereferentiedata uit de onderstaande bronnen. We hebben AI gebruikt om deze data systematisch te verzamelen, te kruisverwijzen en samen te stellen tot leeftijdsgebonden benchmarks. We geloven in volledige transparantie — hier komt onze data precies vandaan.
Naarmate meer coaches en spelers metingen invoeren in CoachBall, vervangen we de referentiedata geleidelijk door geaggregeerde live data per sport, metric en leeftijdsgroep.
