LTS Time question

I have a WebCore graph, that is fed off of an LTS. In the LTS options, the first three are Duration of storage to maintain, but then after that is Attempt to Store Data Every X Hours*, then Time to Start Storing Data.

What exactly do those last two mean? If I have WebCore set up read the sensor every 10 minutes, how does this fit in storing in hour increments? And what is the start time?

The "Attempt to Store every..." sets the time between collection runs

The "Time to Start..." allows you to have it collect for example at 30 mins past the hour...ie so you can normalize the collection and offset it within an hour

So setting "Attempt..." to 2 and Time to start 00:30

Would mean every two hours starting at 12:30 AM, so
12:30 AM
2:30 AM
4:30 AM
....

Generally storing the event changes may be better for 'not missing things', but there are uses cases you just want to poll / average
