Nearly a perfect split too. What is the opposite of "pathetic?"Splitter!
Supercharger - Guin, AL
Surprised to not find this here yet. Construction of a 12 stall, 250 kW supercharger is well underway at 5750 AL-44, Guin, AL 35563 (Holiday Inn). See here for progress video. @Pluto , can you add this to supercharge.info?teslamotorsclub.com
On I-22, Guin, AL splits 129.3 miles, 60.5 miles from Tupelo, MS and 69.9 miles to the end at I-65 in Birmingham, AL. I-22 is currently being extended at the end about a mile to US-31.
This is currently #18 on the list of gaps.

I can't believe you all passed up the chance to say the opposite of "pathetic" is "apathetic".
(I'll see myself out.)
Google "antonym pathetic" gives "admirable excellent".
Another site gives: cheerful excellent glad good happy joyful wonderful useful worthwhile
So, I have to say that it's quite a happy splitter. Although, I'm not sure that in in the long term you want it to be that happy. It would probably be better in the long term cheerfully to take off 40-odd miles at a time.
While the 50% splitter is great, I'll also add that having another Supercharger 20 or 30 miles away can enable a faster road trip as one can shoot for the farther one but have the closer one as a backup in the event of higher than expected energy consumption from stronger wind, precipitation, etc.
50 miles is seasonally flexible, handles round trips, and is fault tolerant for longer travel.
Once you get down to 25 miles I think you're getting to the point of not doing full journey planning, but still having to double check that the site you're going for is up ahead of time.
I think 10 miles is the point where you could use the "low fuel light" approach.
However, that's assuming no difference between locations and adequate capacity.
50 miles is certainly an arguable optimal separation.
Clearly, there's no single, perfect, distance, for all situations, and, of course, it will depend a lot on what is available around the desired location. However, I tend to try to have about a 10% SoC for margin on arrival. 10% is ~25 miles of range with a Model 3 or Y LR. If I've planned for that 10% and find myself is a strong headwind, precipitation, grade, detour, etc, it starts to eat into the 10% making things a bit uncomfortable. If one can stop ~25 miles earlier, that relieves pretty much all stress for those last ~20 minutes.
~25 miles is also a distance that can limped back to with that 10% margin, should one arrive to find a site down completely (we've only had that happen once - power outage in Albuquerque).
50 miles, of course would be great as well but you're going to have to 'bail out' from your plan nearly an hour before arriving at your destination.
I've found there are often EA or Chargepoint stations within 20 miles of Superchargers, however, their speed (mostly time to get a charging session started) and reliability are so bad that they contribute their own stress to the trip.

I think that there are geographical differences in optimal spacing. The eastern and southeast United States is denser with interstate highways that are proximate to each other. There are also cities and towns with adequate infrastructure. Travel on federal and state signed highways intersect with interstates with a lot more frequency.
In most of the west and Great Plains it is another story. There aren't that many opportunities on Interstate 10 east of El Paso or between Indio and Blythe/Ehrenburg. There are major federal and state signed highways that provide needed connections that rarely intersect interstates: US2 across Washington into Idaho, Montana, North Dakota and into Minnesota has a couple SC near its junction with US97 and again in the Spokane area. US95 is getting a SC between Winnemucca and Boise, then there is nothing until it crosses I90 at Coeur D'Alene. Sure, these highways generally have low traffic counts, but nevertheless they will be needing some sort of coverage eventually. I would doubt that Tesla would opt to install Superchargers every 25 miles on US2 or on any of the north-south highways that connect towns in Kansas, Nebraska, and the Dakotas.
Unlike gasoline stations with convenience stores attached, it takes some time to replenish the battery to an adequate amount before departing. If charging took 6-7 minutes like refueling an ICE, it would not matter what was available at the SC location. But a 15-30 minute charging time gets tiresome very quickly if there is nothing to do other than wait.
Anecdotes from newer owners of Teslas simply rely upon the navigation to determine their stops. It makes no difference what their SOC is upon arrival. They see that the touchscreen says it is now safe to continue their trip, so they unplug and leave. Or, they take a little extra time getting a snack and arrive back with more than enough charge to make the next scheduled stop but not enough to make the Supercharger another 40 miles distant (according to the navigation.)

Superchargers needed 4/30/2023:
Interstates:
US Numbered Highways:
Still eating away at the totals.
It looks like Milan, NM (Grants, NM area, findus Q2 2023) is under construction, but it's not fully confirmed as a Tesla Supercharger. It would be a "150" Interstate splitter and is #8 on the table.
Interstates:
| Max Separation | 03/31/2023 | 12/31/2022 |
|---|---|---|
| 25 | 1311 | 1332 |
| 50 | 442 | 458 |
| 75 | 193 | 203 |
| 100 | 72 | 81 |
| 125 | 25 | 30 |
| 150 | 12 | 11 |
US Numbered Highways:
| Max Separation | 04/30/2023 | 12/31/2022 |
|---|---|---|

What does the number for US Numbered highways look like at 200 and 250 miles? Is it time for a new "Largest gaps" thread for them? (I mostly care about US 30, US 50, and US 6. But there are many others with very large gaps.)

| 200 | 256 | n/k |
| 250 | 166 | n/k |
Do remember that for US Numbered Highways:
- it's following the highway even where there's an obvious non-Interstate shortcut.
- there are a fair few concurrencies so the actual number required would be lower.
There are 139 gaps above 250 miles, even if all "Permit" and "Construction" locations open.
Right, yes, Gallup to Albuquerque is ~145. So Milan, NM would cut the 125 and 100 by 1. 150 would be unaffected. 75, 50 and 25 would be unaffected because it's a 60 + 80 split.

On I-20, Santo, TX will split 120.2 miles, 56.9 miles from Cisco, TX, 64 miles to Arlington - E Bardin Rd, TX. Quite close to an ecstatic split.
Supercharger - Santo, TX
TDLR filing for a Supercharger at the Circle H fuel stop in Santo, TX along I-20. Just west of Fort Worth. I think there is a typo on the address in the TDLR filing though, the address in the filing doesn't seem to exist. I think they meant 87125 I-20, Santo, TX 76472 and NOT 87121. The filing...
