The Fitness Tracker That Added Extra Steps

Kendra and Dominic wore matching fitness trackers on their wrists. Every week, the app showed each person's step count. They had a small, friendly bet about it.

肯德拉和多米尼克手腕上戴着一模一样的健身手环。每个星期，应用程序都会显示每个人的步数。他们为此打了一个友好的小赌。

On Monday, Kendra checked her number and laughed out loud. "Twenty-two thousand steps? I didn't walk that far!"

星期一，肯德拉看了看自己的数字，大笑起来。“两万两千步？我没走那么远啊！”

"Maybe you did," Dominic said. "You took the dog out twice."

“也许你走了，”多米尼克说，“你带狗出去了两次。”

"Not twenty-two thousand steps," Kendra said. "Something is wrong with this thing."

“也不至于两万两千步，”肯德拉说，“这东西肯定出毛病了。”

At school, Dominic checked his own number too. His steps were very high, and that was not normal for him. They both looked confused and sat down to talk about it.

在学校，多米尼克也查看了自己的数字。他的步数高得离谱，这对他来说很不正常。他们俩都一脸困惑，坐下来聊这件事。

"What did you do yesterday?" Dominic asked.

“你昨天做了什么？”多米尼克问。

Kendra thought about her whole day. "I washed dishes. I folded laundry. I practiced piano for an hour."

肯德拉回想了自己的一整天。“我洗了碗。我叠了衣服。我练了一个小时钢琴。”

"That's it," Dominic said. "The tracker counts hand movements as steps sometimes. Piano and dishes probably confuse it."

“就是这个了，”多米尼克说，“手环有时会把手的动作算成步数。弹钢琴和洗碗大概让它搞糊涂了。”

Kendra opened the app and found a page about accuracy. It explained that fast movements can look like walking steps. The sensor gets confused easily.

肯德拉打开应用程序，找到一个讲准确度的页面。上面说，快速的动作可能看起来像走路的步子。传感器很容易被搞糊涂。

"So my piano practice basically walked me across town," Kendra said, smiling.

“这么说，我练钢琴等于走着穿过了整座城，”肯德拉笑着说。

They decided to fix the bet. From now on, they agreed to compare real walks and runs. House chores did not count.

他们决定修改赌约。从现在起，他们约定只比较真正的步行和跑步。家务活不算。

The next morning, they walked to school together. They checked their trackers side by side, and the numbers finally matched.

第二天早上，他们一起走路去学校。他们并排查看了手环，两个数字终于对上了。

"Fair bet," Dominic said, holding out his hand.

“公平的赌约，”多米尼克说着，伸出了手。

Kendra shook it. "Fair bet," she agreed, and they walked through the school gates.

肯德拉和他握了握手。“公平的赌约，”她同意道，然后他们走进了校门。
