Introducción

Puedo escribir a un ritmo moderado, usando la distribución del teclado QWERTY. Pero si una palabra como yellowwooddoor tiene un montón de letras repetidas, toma un poco más de tiempo escribirla. Peor aún es cuando una palabra como "saltar" tiene el mismo dedo utilizado para varias letras consecutivas diferentes.

Este es el tiempo que me toma escribir letras en cada dedo (medido muy poco científicamente):

Las columnas son Nombre del dedo, pulsaciones de tecla / segundo, segundos / pulsación de tecla y las teclas utilizadas por cada dedo

Desafío

Dada una cadena como entrada, ¿cuánto tiempo lleva escribirla?

• El "temporizador" comienza en el momento en que se presiona la primera tecla y finaliza cuando se presiona la última tecla. Solo está contando el tiempo entre pulsaciones de teclas.
• Este es el código de golf . La respuesta más corta en bytes gana.
• La presentación puede ser un programa completo o una función.
• La entrada y salida de la forma que desee , stdin / out, parámetros de función, archivo, no importa.
• La salida debe tener una precisión de al menos 3 decimales (+/- 0.001 para el error de redondeo está bien). 0. a la izquierda para números menores a 1 y línea posterior opcional.
• La entrada será una cadena que contiene (minúsculas) az, 0-9, espacio, punto y coma, coma, punto y apóstrofe.
• Siempre escribo espacios con mi pulgar derecho.
• Utilizo los dedos de escritura táctil normales (también puede consultar la tabla anterior para ver las asignaciones de teclas con los dedos).
• Código de referencia utilizado para generar casos de prueba

¿Cómo?

Almacenar retrasos

$g$$0\le x \le17$

g = x => 10 / Buffer('4.2.5-75E6?3>4=4AA')[x]

$x$

• dos veces el número del contenedor para obtener el retraso de la misma letra
• dos veces el número de contenedor + 1 para obtener el retraso para diferentes letras

'4.2.5-75E6?3>4=4AA'$10$

$5.2$chr(52)'4'
