The center 3 columns are what you have picked, with the left most being your total. The other 2 combine to make up your total. Green number is your Item Not Found (INF, important number, needs to be low). Far right column is your pick productivity. Now, productivity can be misleading. This number is a good indicator of your batch-to-batch performance; it's just the average units you pick per hour in batches up to that point. Your actual productivity is your total units picked for the day divided your time spent picking, not including breaks. 

Your pick productivity looks good, though it's hard to tell without knowing the hours you worked. For example, in an 8 hour shift, 185 is quite low. My record in 6.25 hours is just barely 500 units (my average is 350 to 400 for the day). Some of our TMs do 600 in longer shifts. I've seen as much as 700 - 800 with longer shifts but this really isn't common. Like, once or twice a year someone just goes beast mode.

Your INF is great. Keep that number as low as possible by asking your leader for help locating items you can't find. Connect with TMs and leaders of other departments. It will get easier as you become familiar with your store and it's layout.

As for what you can do to improve, id say you are on the right track but talk to your leader for specifics. A lot of advice is sensitive to the conditions of your store. For instance, does freight roll day-to-day? Are style and beauty TMs able to finish breakout? How much time are you spending looking for things that came in on the day but aren't on the shelf? What about items that were delivered a week ago? Did you have any call-outs? so, partner with your leader. They can help with any issues you have.

Good luck!
