### Description

I write some test code and create one pull request which include just one commit. Then I get coverage data via [this API](https://codecov.io/api/gh/qiniu/goc/pulls?state=open).Let’s focus on the data where issueid equals 130.

Here is my question:

1. Why timestamp not equal updatestamp? After I create the pull request, what does codecov do?
2. There ars two comments of coverage bot on github, the first one says `Merging #130 (c819512) into master (ddb6dfb) will decrease coverage by 7.42%. The diff coverage is 0.00%.` The second says `Merging #130 (c819512) into master (ddb6dfb) will decrease coverage by 0.03%. The diff coverage is 0.00%.`

I refresh the page after a few seconds, then only the second comment can be seen(decrease by 0.03%).  
Why there are two comments? Why the decreased number in the comments is different? Why the first comment disappear after a few minutes?

@fansi404,

1. `timestamp` is the author date which you can see from git (`git show c81951296d3585542d770708e678d1e00df51d32`)

```auto
commit c81951296d3585542d770708e678d1e00df51d32 (HEAD -> fansiqiong/master)
Author: fansiqiong <fansiqiong@qiniu.com>
Date: Thu Nov 12 11:39:02 2020 +0800

```

`updatestamp` is Codecov specific, when we updated the pull request and acknowledge uploads.

1. I’m going to guess this was a race condition with GitHub. We attempt to only comment once and edit the original comment. I’m sorry here for the confusion.
