Chain rings shifting has 4 positions when it should have 2
So when I shift my chain from big to small, there seems to be 4 clicks I can do with the shifter rather than 2. Is this normal? I've tried to adjust the tension and position screws on the derailleur with no luck.
Video of my issue: drive.google.com/file/d/16vxGaWAHCv6s92yVgMMi-06IW9brQ-aI/view?usp=sharing
Any suggestions?

The video does not provide the model shifter you have. Many front shifters have 4 positions in order to be able to trim the front derailleur when riding cross chained

It's normal. They're called trim positions. Some derailleurs have them, others don't.
You can use them when cross chaining to avoid chain rub on the front derailleur.

What bike?
My bike has Sora components, but the shifters are MicroShift brand. The front has 4 clicks for trimming the front derailleur.

My Trek with Campy ergo brake /shifters has the trim clicks also. The rear derailleur is indexed and indexes nicely. The front derailleur is friction shifting. Takes two clicks to shift from the large chain ring to the small one and vice versa.

Campy Ergo left shifters are definitely not 'friction'.

OK the front has index clicks but more than needed to get to the next chainwheel. Not like the rear derailleur. I finally dialed it in after waching the you tube video from Arts Cyclery. It is normal to have several clicks with the front derailleur.

cxwrench,
Sheldon Brown does a better job of explaining the Campy Ergo front shifters than I do, technically they are not indexed shifters in the front. :
"Campagnolo Ergo shifters. These are indexed on the rear, but not in front. The Ergos are not strictly "friction" shifters, as they do "click" when you shift them, but they have many "micro clicks" permitting considerable "fine tuning" of front derailer position."

Yes, you're right. The need for trim positions however is dictated by the FD design. For example, with SRAM Yaw derailleurs they're not needed and you can crosschain without chain rub if properly set up.

I sometimes wish my Shimano Altus triple chainring had a way to trim the front derailleur. It uses a twist grip shifter and while it allows for a trim adjustment when I make the shift sometimes I'm not comfortable when it clicks into position even after a few adjustments.
I see why some prefer a friction shifter for the front derailleur. The back 7 speed freewheel's
shifting seems pretty good once properly adjusted though.

I use Campy Ergo on my main bike and had a hard time when I rented a 105 11sp equipped bike and also once a 10sp Ultegra because I couldn't get rid of the chain rub the way I'm used to. Be happy you have trim.

To be fair, SRAM Yaw FDs are a huge pain in the ass to set up properly, but once done, they work perfectly.

What I'm wondering is: why is SRAM universally known to be unable to make a good FD when they're the only ones who can manage a FD that needs no trim and doesn't rub? Why can't Shimano and Campy do it too?

With the Campy I have I like being able to get the front just right. To get on the big ring I shift it all the way and then back off one click and I'm good for all 10 cogs. For the small ring there is no one position that is good for everything. Each click though is small. It all feels very natural, like friction but not.
For me, more time consuming means it's a pain in the ass. I have little free time unfortunately.

Hold on...you're telling me that your life is so busy...that you have so little time that you can't find an extra 5 minutes at the most to adjust a derailleur? One time? I hope you're really good at changing flats on the road, if not your life might fall apart.

Anyway, thanks for judging me. Maybe someday you'll discover how having a child and a wife that works during your free time affects your ability to wrench before 10pm and your ability to ride after 9am.

Barely, but I do have my moments.
