That might be due to different versions/features enabled. I am using
pacman's package. I posted my complete version in a previous post.

Also, David (hyperfine creator ig) found the missing 2s.
https://github.com/vim/vim/blob/4c0089d696b8d1d5dc40568f25ea5738fa5bbffb/src/main.c#L2802-L2807

Passing `/dev/null` as script file doesn't halt the execution and
instantly shows the actual startuptime.

```bash
$ hyperfine "vim -N -u NONE -i NONE -X -cq -s /dev/null"
Benchmark 1: vim -N -u NONE -i NONE -X -cq -s /dev/null
Time (mean ± σ): 36.0 ms ± 4.5 ms [User: 23.6 ms, System: 11.8 ms]
Range (min … max): 30.9 ms … 49.7 ms 79 runs
```
