This is roughly what the table looks like yes. We've found that because players do these tasks so often, they must really love them, so we increased the set tasks and reduced the random tasks because there's enough RNG in the game.
Seriously though, yeah there's a set path for each of the three paths. So we refer to the daily reset task (top entry) as the Daily, which changes based on your level (Low, Mid, or High tier tasks, though honestly they were set up in such a way that it doesn't take long to reach high). Then the following three tasks we refer to as Task A/B/C. Each of those follow a set path of about 15-20 unique tasks each, before they dip into a pool of almost 40 generic repeatable tasks. Which I imagine most of you are in now. As one of the later updates was the randomized task conditions, a lot of the hard-coded tasks are still in there, so they'll appear slightly more often than the randomised ones, as they're all only one entry. That being said, there are a few copies of the random task in there, just with different rewards.
@WarLordNo1: Great to hear! Glad your tasks are fixed.
