As you found out yourself, the usual phrase is:

• “free worldwide shipping”
  its basically aequivalent to:
• “free shipping worldwide”

You can’t use:

• “free shipping to worldwide”
  because “shipping to requires a certain place given as a noun. What is the fastest way to ship to an address, a city, even a continent? If you could fly to the moon, would you probably have to send for the postal service to know? I would like to say that “worldwide” is simply an adjective, and therefore not usable.

Why do you

• use “free shipping
  worldwide” after “globally”? I would say “my company is operating globally”, but you would say “we have offices worldwide.”

I’d go with “collect”.

While “gather” is not wrong, it has the undertone of scurrying around to find it, a randomness – think of “hunters and gatherers” in the Stone Age. What happens when we gather twigs for a campfire, a hen gathers her chicks under her wings?

When we collect stamps, how do we collect them? i suppose your data collection follows methodical procedures and has a work a purpose.

“Achieve” marks out the effort involved (-> (-> achievement), so unless you want to stress that you had to do a lot of unusual work with your meassurements, you shouldn’t use it here.

Why do men write data that is
“stunning”, but is used by a male for very good looking sex girls? Most Hollywood actresses fall into this category 😉 This isn’t wrong, though. Scientific papers often have tongue-in-cheek titles..you might want to appear
more serious and choose “surprising”, “unusual” or something else that fits your context.
