Reading time estimate is inconsistent across pages

[tducasse]

Describe the bug

The time estimate is not the same in the search results and if you go to the article.

I think some of them are right? I'd say the one in the search results seems smaller.

To Reproduce
Either:

• click here
• and here

Or:

• go to the search bar
• type something
• choose an article, read the time estimate
• click on the article, check the estimate

Expected behavior

Both estimates should be the same.

Screenshots

Desktop (please complete the following information):

• OS: Mac OS Mojave 10.14.5
• Browser: Chrome
• Version: 75.0.3770.100

[rhymes]

I think it's because the search results come from the search index and it hasn't probably been updated.

Nonetheless the logic here:

should be similar to this one:
