I'm basically trying to figure out how to delineate my stakes profit from my share of the house edge profit. When I click on the 'commission' button in the 'History' tab, does this show my investment increase due to house edge, and the commission taken from that for just-dice, or is there a different way to view what I've gained from my share of the house edge?
I don't think the site makes it very clear where your profits came from.
Let's look at a random user for an example. This guy hasn't touched his investment for the last couple of months, so things aren't complicated by invest/divest events.
Here's his "investments" report:
And his "commission" report:
Looking at the most recent week, we see his "profit" is shown as 0.00612616 and his commission is 10% of that. That is his profit from the house edge. It doesn't include his staking profit.
Each time we stake a block, 90% of the block's reward is distributed to investors, and 10% is taken as commission, immediately. Your share of the block reward is added to your investment, and also to your "base", which means it won't be seen as "profit" at the end of the week, and you won't have to pay any further commission on it.
If you look at the guy's "base" figure and how it changed this last week, you'll see it went up from 133.78519775 to 136.04771387. That's a rise of 2.26251612, and represents his total profit for the week, including from staking.
Finally, if you look at
https://just-dice.com/wagered.txt you can see the site profit and staked amounts per day. For the week in question we see:

1089.53447718 8011.70520000
ie. the site staked 8011.70520000 CLAM and won 1089.53447718 CLAM.
The guy we're looking at has no offsite investment. His 'base' went up by 2.26251612 for the week, meaning that 90% of his total profit before commission is 2.26251612, and so his total profit for the week before commission was 2.26251612/0.9 = 2.5139068 CLAM. We already saw that his profit from the house edge before commission was 0.00612616 CLAM, so his profit from staking was 2.5139068 - 0.00612616 = 2.50778064 CLAM.
Note that his profit from staking is around 400 times bigger than his profit from the house edge. That's because the site made 8 times more from staking than it did from the house edge, and the average investor has roughly a 50x offsite investment. 50 * 8 = 400.
Does that make more sense now?
If you have any questions I'll do my best to answer them. Maybe post your 'investment' and 'commission' reports if you have specific questions about them.
