There seems to be something wrong with "profit" at the invest charts. From July 25 2018 to today I made 7.158% on my investment, while the graph shows a profit of 9.39% based on the initial bankroll on July 25 2018. Bankroll has actually kept on dropping since then, so profits should actually be higher than that if adjusted to the bankroll that existed every day (which is something that would take a lot of time to calculate, but it'd be higher than 9.39% for sure). This makes me think that what is shown in that graph aren't investor profits, but "profits" before the 0.3% fee you charged investors every hour (on wagered amount), so around 70% of what investors actually made.

I believe we've talked about this before. I've made a fairly long post about this when you asked last, which you might have missed. Since you never followed up on it, I assumed my post answered the question.
I'm gonna be lazy and quote it here, instead of writing it up with recent numbers. Same as back then, feel free to ask further questions, if you still don't understand something after this.

I think I understand your confusion and I have previously discussed this topic with someone else who had a similar question (IIRC it was thenerd314, who afaik reads along this thread, so if he wants to chime in...).
Since I don't quite recall whether it was in this thread, in my tracking thread, or in the chat, and since searching all 200 pages/my 5000 posts would be a lot for me to go through,
I'll briefly sum up the essence of it once again. Feel free to follow up on my explanations, in either of the three places.

For better understanding, I will use the numbers from the BTC chart as examples (also, since BTC is the most popular together with ETH, it likely is the one you were looking at or others would have questions about).
I'll look at the chart in a 3 month period (meaning from Oct 18th to Jan 19th, you can replicate the view I get with the 3mo button).
For those reading at a later point, or not familiar with the chart, this are the numbers shown:

Bankroll Size: relatively stable, starting at 1497.6BTC, ending at 1477.7BTC, lowest at 1342.8BTC, highest at 1519.9BTC,
for the sake of making an estimate, I will appraise the bankroll size to be fixed at 1480BTC in my calculations.
This introduces a small error, but the accurate calculation is too complicated and not needed to explain what I want to show.

Total profit: starting at 1198.15BTC, ending at 1235.31BTC, which equals a profit of ~37BTC for all Bitcoin investors over the last three months.

What I assume you did (and correct me if I am wrong, but that's the misunderstanding I helped clearing up in the past) is the following:

If the total profit grew from 1198 BTC to 1236 BTC, meaning an increase of 3.1%, then my investment should increase by 3.1% as well.
However, this is wrong. The total profit line/number tracks investors profit from the very beginning of public investments and shows the raw profit,
without taking bankroll size (the second line in the chart) into consideration.
To calculate the increase of your individual investment, you have to take this number and weight it against your share of the bankroll.
With Bitcoin, and the numbers being so close together (1200BTC and 1400BTC), people sometimes forget about this, since the above increase is "realistically" possible.

If we do this with a profit of 37BTC and a bankroll of 1480BTC (our earlier appraisal), we would get an increase of 2.5%, not 3.1%.
This should be closer to the return you have seen.
However it still is not 100% accurate, since the bankroll size changed due to new investors and leaving investors,
thus at some points your investment had a lower share of the profits and at some points it had a higher share.

I hope this explanation has helped some of you to understand reading the charts and gathering the information from them they desire.
I would urge everyone with more specific questions about investments (or a follow up to this) to head over to the dedicated investment (tracking) thread maintained by me:
https://bitcointalk.org/index.php?topic=2445163.0
This way, discussions like this one can be easier found by others having the same questions, and do not get burried within hundreds of pages about other aspects of the site.
I'll also link this response specifically in my "special posts" section over there to make finding it easier in the future.

I used the second way of calculating it. These are the exact numbers (in Bitcoins):

July 25 2018. Bankroll: 1521.37. Profit: 1133.86
Today (now). Bankroll: 1281.73. Profit: 1276.78
So, assuming bankroll didn't change, investors should had made in that period of time: (1276.78-1133.86)/1521.37=9.39%
As bankroll kept dropping, profits for someone that stayed invested all the time would actually be higher (as you said, to calculate that more accurately, even if just daily, would take a lot of time).

However, during that time, as an investor I only have 7.16% more than I invested. This number makes sense if the graph's "profit" isn't actual profit but "profit" before the hourly 30% of edge cut (so without that fee I would have made around 10%, which is approximately what the graph represents if we consider that bankroll dropped during that time).
