# wrong slider time - geogebra bug?

Cecilia Lucía Gigena shared this question 2 months ago

Manual says that a slider is supposed to take 10 seconds to run from side tu side, unless a velocity different to 1 is setted.

I timed with a chronometer my slider with velocity = 1, and... No, it takes WAY MORE than 10 seconds to complete 1 cycle.

How can I know the ACTUAL period? So that I can modify velocity accordingly. (I keep timing but it's not an accurate measure.)

No es posible pues depende también de la velocidad del ordenador usado y de las paradas imperceptibles que puede haber en el movimiento

```WAY MORE than 10 seconds
```

It's hard to measure accurately because of human reaction time. I have to turn a chronometer AND the slider on at the same time. I tried turning a chronometer on around 10 seconds before turning the slider on, so that I can sort of "practice" to make them match, and then substracting 10 to the measured time, and I found around 13 seconds (I measured 23-24 seconds and substracted 10).

Please try to measure yours and we'll see if we both have the same issue. I am attaching my file but I'm not sure if it actually helps, considering what mathmagic said.

por curiosidad he hecho la siguiente prueba en version 5 version6 y en la classic online

un deslizador con min=-5 max=5 speed=1 incrementando

he puesto a funcionar el deslizador y un crono al mismo tiempo durante seis recorridos completos en los tres casos

en uno he contabilizado 61 segundos en otro 59 segundos 60 centesimas y en el otro 60 segundos justos

o sea que la temporización es correcta desde mi punto de vista (claro, que todo ha sido con el mismo ordenador)

Hi,

My measure = 10s
