For fun, I decided to implement this using the abovementioned module. I split it into two tags for readability but there's nothing stopping you from nesting the expressions into a single monstrosity:

Tag 1, getting the highest tag value of our group (assuming the tags are nicely ordered and 1-indexed):

```auto
max(
	forEach(
		tags(
			forEach(24, stringFormat("[default]path/to/tag_%d", idx()+1))
		),
	it()[1]
	)
)

```

Tag 2, getting the max of Tag 1 over time (see [Tag Max Value no SQL - #2 by pturmel](https://forum.inductiveautomation.com/t/tag-max-value-no-sql/35649/2))

```auto
objectscript("args[0] if state.get('max') is None or args[0]>state.get('max') else state.get('max')\nstate['max']=__retv",
	{[~]Tag_1})[0]

```
