Options 2 or 3 seem most logical, but I'd go for a "Move" equal to half normal standing Long Jump distance starting from the wall the character "bounced" off of. This assumes that your last jump before you clear the wall has you taking off at an approximately 45* angle & you are able to push off the wall without about half the forward momentum you could normally muster if you were jumping from flat ground.

It ignores speed loss from previous jumps (since each jump adds energy to overcome the force of gravity) which is built into the maximum height you can achieve with the Tic-Tac maneuver.

Looking at videos of real-life Parkour practitioners, I'd say 1 second per jump, although both characters in your example have superhuman Move scores, so allowing 1 jump per Move/5 (rounded down), or 1 jump per yard of basic Step distance, doesn't seem unreasonable. That allows Dar, who's capable of booking along at 22 mph without using Extra Effort or Running skill to clock 2 jumps/sec., while his companion, who merely chugs along at 18 mph, is stuck performing just 1 jump/sec.

Again, looking at video of RL world-class PK experts, I'd say "none of the above".

Take a look at the examples here:

Given a sufficiently rough wall or a narrow "chimney" where you don't loose too much height due to gravity before you encounter a new surface to jump off of, you can go way higher than Basic Move/2 (e.g., the chimney climb at 0.44 on the video where the free-runner reaches at least 5 yard/15 feet before pulling himself up the rest of the way. The blocks provide handy measurement scale of ~1 meter/3-4 feet).

If you want to create a house rule, maximum tic-tac height in a "chimney" less than 2 yards wide could be as high as [Basic Move x 1] yards.

Additionally, the Tic-Tac technique should be able to boost your effective Basic Move when determining maximum height.

It's also clear that if you do run out of jumping energy, you should be able to immediately roll vs. Climbing skill to cling to a wall with handholds and then climb the rest of the way up. Alternately, you might be able to roll vs. Acrobatics skill to grab a projection with your hands and haul yourself up on your next turn, gaining height equal to your body length.

Turn 1: Jumping skill roll to gain half maximum High Jump distance (or maximum Long Jump distance), followed by Acrobatics roll to nail the first Tic-Tac.

Turn 2+: Success on later roll allows you to gain height per RAW. Maximum height is based on success rolls, up to maximum possible height plus initial jumping height.

Would you allow them a DX/Acrobatics/Climbing roll (at some penalty) to catch the edge of the wall since part of their body is above the point they are trying to reach?

Again, looking at the video, it's obvious that just about all Parkour Tic-Tacs where the free runner intends to clear the wall end with them grabbing the top of the wall, pushing off with their feet and using Acrobatics or Climbing skill to haul themselves up & vault over the wall.

That means any successful skill roll where the character gains enough height to get their hands within grasping distance of the top of the wall should be able to make a DX, Acrobatics, or Climbing skill roll to grab the top of the wall and hang on.

To simplify things, assume that the last Acrobatics/Jumping skill roll includes the option of grabbing top of the far wall and automatically hauling yourself up and vaulting over the edge on your next turn, so that you land on the far side of the wall. This could be considered to be a modified "Step" maneuver.

(e.g., -2 or -4 roll versus -1 if within ¼ of their height, -2 if within ½ of their height, -3 if within ¾ of their height, -4 if within their height, and -6 if within their reach above their height).

I wouldn't penalize based on remaining distance unless something happens which seriously slows the character down. Instead, apply a standard penalty to each turn of activity, based on distance between parallel vertical surfaces (perhaps -1 per 1 foot beyond 3 feet), RAW modifiers for Parkour techniques, and the modifiers to Climbing skill for surface slickness, surface slope, and available hand/foot holds.

Bad rolls will penalize overall effort in reduced height gain from a given jump, which in turn increases number of rolls needed, which adds further chances for failure/critical failure.
