I usually do mine at a shop.

Change the oil and oil filter after 150-200km.
Do this again after 1000km.

I personally change mine every 1000km until 4000-5000km.

After this change to fully synthetic oil.

No harm comes in changing the oil early or too regularly, but it's important to change the filter after a few 100kms as a new engine will still has metal in it that will run into the oil, best to get it out soon.

Don't run fully synthetic oil until the break-in period is over.

Yup, change the oil filter after 150km, and again after 1000km.

Change the oil and oil filter after 150-200km.
Do this again after 1000km.

And change it again when you change to fully synthetic oil.

Changing it more than this will not do any harm. It's a good thing to care of.
