As a newbie, loo() comparisons cause some confusion. Could you please have a quick comment?

**Example 1**: m2 is better since elpd_diff is >3 times higher compared to se_diff? Or the difference is insignificant due to so small numbers?

```
Model comparisons:
elpd_diff se_diff
m1 0.0 0.0
m2 -0.5 0.1
```

**Example 2**: m2 is worse as elpd_diff is >3 times higher compared to se_diff

```
Model comparisons:
elpd_diff se_diff
m1 0.0 0.0
m2 -15.5 5.1
```

**Example 3**: models are equal as elpd_diff is not 3-5 times larger compared to se_diff? But what about so large se_diff?

```
Model comparisons:
elpd_diff se_diff
m1 0.0 0.0
m2 -0.3 182.4
```
