There are incorrect percentage calculations on the ‘Overview’ page.
Example—
I noticed that my Mythical Island - Mew pack indicates 0% chance of getting a new card and that I have 32 of 32 cards. The game indicates there are 68 diamond and 7 star cards, for a total of 75… not 32, like the tracker indicates. (I’m still missing #46 Aeordactyl ex, diamond card; and many of the star cards). So the percent chance of getting a new card shouldn’t be 0%.
Additionally the math seems off…
On my orange Charizard pack area (the most likely pack to get a new card from), it indicates I have an 11.5% chance of getting a new card. But the bar graph on the side for “charizardpack” indicates I have 23 out of 25 cards, which is 86.95%, remainder 13.05%. Where is 11.5% coming from?
Not sure where you get these numbers from, maybe you can attach some screenshots to clarify. For me it looks fine:
Regarding your second question, the bar shows you the percentage you are missing from the pack, this is not the same as the percentage of getting a card you don’t have yet from the pack. For example, if you are missing a single diamond card, the chance of getting that card is much higher than if you are missing a crown rare card.
The calculation of getting a missing card is much more complex based on the rarities of your missing cards, taking into account the pull rates of those rarities and how many of them are in each pack.
My bad on the first part…I didn’t realize I had a 1 star filter clicked, until I just double checked!!! DOH! Sorry for the false alarm, and wasting your time. (after removing the filter I see 65 out of 86 cards)
As for the second part… Yes, that makes sense. I was over simplifying.
