[20:15] Now, as I feared, the Tetrinsics are sticking out quite a bit. The good news though is that I can have 19mm spacing for Finger2-4 and a 20mm spacing with 4 degree tilt on Finger5. Finger5 is also 4mm lower than the others.

That battery is currently on thin ice. On one hand, I don't really want to give up a 4.8Ah battery. However, I'd like the battery to be easily replacable anyway so I could always bring a spare with me.

If I can't find a suitable battery at all, the Forced Solution Solve I sent from Tetrinsic might be reflected back. This is a description of what I'm talking about between Me In The Past and Me Sometime Later:

1. Solve a solution for Tetrinsic 2.0 with TFT.
   1. Solution solved with 1 warning: It's almost 53mm long. The Timespy solution may fail.
2. Send a solution resolve request to Timespy.
   1. A solution to increase the length of Timespy... failed, due to exceeding a maximum solution limit of 70mm set by Me In The Past. Reason: Ergonomics.
   2. Attempting to discover a new battery solution. (<--I am here)
   3. A solution... fails. (<-- what happens if I can't find a decent battery and don't want to connect umbilical power cords so that Timespy doesn't run out after 3 hours)
   4. A forced solution solve... fails. The new solution limit for Tetrinsic is <43mm.
3. Send a solution request to Tetrinsic 2.0 with TFT.
   1. A solution... fails, due to geometric constraints.
   2. The solution... is rejected. (<-- I don't want this. Tetrinsic with a digitally adjustable aesthetic looks really nice, even if I'd only be able to see it when I'm not using it.)
4. Solve a solution for Tetrinsic 2.0 with white LED backlight. (<-- This is what's likely to happen next...)
   1. A solution... fails, due to geometric constraints:

      That wasn't supposed to happen.

5. Solve a solution for Tetrinsic 2.0 with backlight and single track. (<--Ok I've just skipped over and I'm here now. I need to see where this is going because it doesn't sound good!)
   1. A simulation produces a near-failing warning: Ergonomic and grip concerns issued. There is a very noticable difference in feel and confidence compared to 2 tracks.
   2. Thus, a solution... may fail.
6. Recompute a simulation with real world simulation metrics.
   1. A simulation... fails, in part due to walking vibrations causing loss of grip; this increases typos and thus reduces thought flow to a solution failing level. Additionally, finger pressure on a single ball became ergonomically uncomfortable after approximately 1 minute.
   2. (Auhh nouh say it isn't souh!)
7. [Insert more back and forth solution reflections and recomputations]
   1. Due to time constraints, 2 solutions cannot be persued. Additionally, due to Timespy having a higher solution coverage (how many current and future problems the solution mitigates or eliminates) compared to Teti, Tetrinsic 2.0... fails.

Wow. Who knew that this project, which started off as a "Mn... might as well see what I could do..." has higher priority than my main PC. I guess this is the Steam Deck Effect, where some users report using their £349 not-a-console over their £2,349 gaming PC.

Anyway, it seems that finding a suitable battery has much higher stakes than I originally thought. No pressure, Me In The Recent Future.
