Cada cifra, con su fuente.

Cómo leerlo

Muntin hace tres tipos de afirmación, y trata cada uno distinto:

• Investigación externa — citada en línea a su fuente primaria (series estadísticas oficiales, investigación con nombre, páginas de precios de plataformas) y fechada. Son las afirmaciones de la lista de abajo y de /claims.json.
• Experiencia de salón — de primera mano, de los turnos de Don, etiquetada como experiencia del operador cuando ningún documento público la respalda. Esas viven en /es/about/, no aquí, porque no hay URL a la que apuntar.
• Ilustrativa — cifras de ejemplo para mostrar un método, nombradas como ilustrativas en el texto para que nunca se lean como medidas. Métodos es la política completa.
