- What do you think about all of this data? Do you think what this data shows also true in the long run, that there's a lot more people know about position these days so they rather fold when someone open raise from UTG?
Whatever the data shows, for such statistics you would need a lot more hands than just several. 
Open-limp is overall very bad and easy to recognize. So I don't even see why I should collect statistics for that.
- What do you think about my suggestion to loosen up my open range (UTG)? Do you think it would invite more action to the hands if I do so?
Wouldn't do that in FR games. 
Rather loosen up late position. 
- I usually open from UTG with (99+, AJ+), is this too tight? I'm thinking about using vonki's range from weekly freebie (22+, AJ+, KQ), what do you think about this? Would it invite more action to the hands?
Nah, I don't like raising small PPs as 22-55 at all from UTG. Most likely you wont even play with them very profitable unless you have huge edge on postflop and know around. You can just take a look how you play with those PPs from your statistics and see if you should even play with them. Otherwise your range seems to be fine, about KQ is practically the same. Depends really how huge edge you have and what opponents you have on table.
