I've created a Rubik's cube timer web app, and each time a user uses the stopwatch, their time is added to a table on the webpage.
With each attempt, an arrow is shown informing the user whether their attempt improved (decreased in time compared to the last attempt) or became worse (increased in time). I chose the down arrow to represent a decrease in time, as that's what seems intuitive to me, and an up arrow to represent increase in time. However, my users informed me that the arrows are confusing and they expected the arrows to be the other way around. With a better score (decrease in time) they expect the arrow to point up, signifying that they did better. Both explanations make sense, but at the same time seem to be confusing. What direction should the arrow point and why, or am I missing something?
I've already looked through this post but it doesn't seem to answer my question.
