It surely did for my baby tester city. I think you are focused on doing 5 rounds every week, which isn't the case for all players.
Those 96 minutes fundamentally changed the tournament for me due to my RL schedule, and they might for many other players whose real lives take precedence over Elvenar.
Even if you want 6 rounds instead of the normal struggle it is very nice to be able to do
1 round on Tuesday
2 rounds wed
2 rounds Thursday with booster buildings
1 clean up round on Friday + full spire (optional, can do spire the day before and take a 4-day vacation)
Saturday & Sunday & Monday OFF completely.
then
tuesday full spire +1 round
Wednesday 1 round before boosts expire.
For a non-boosted tournament and a little break where maybe you only go 20x2 plus some easy 1-6 clean ups.
Guess this works somehow due to different timezones: if I would do this:
1 round on Tuesday
19:00
2 rounds wed
9:24 and 23:48
2 rounds Thursday with booster buildings
14:12 (no clue how you fit in here round 2 as it's at 28:36 and hour that doesnt exist in my timezone)
1 clean up round on Friday + full spire (optional, can do spire the day before and take a 4-day vacation)
4:36 and 19:00
It would fit into a US -5 timezone but that means playing at 3:24 in the middle of the night
I would call this an insane strict time schedule thats not workable for 99% of the players.
I would not advise such a scedule to any player unless that player has some dedication beyond reason.
I was looking at 6 round, btw 3 rounds without boosters in this format is brutal. in the new tournament format each round is only marginally easier (1 province step) it's not like the old format where the first 3 rounds where a lot easier. provincie 19 round 3 is as difficult as province 20 round 2 and provincie 21 round 1. the difference is tiny.
So I do not see how a level 1 polar bear makes thinks fundamentally different in your example. maybe you could squeeze out 1 more round with boosters but you have to go pretty far to strech that one out. the same stretch that make most people ignore round 6 altogether as it's benefits are limited but the costs to reach is are high.
I find polar bear awesome and are a big fan of it, but in combination with timewarp so you get total freedom over your schedule including the 6th round, and once you can fit all fights into 1 day it becomes a gamechanger.
Extremes like the scedule above, or pre polar bear waking up on a saturay morning at 4am to push 6 rounds in 1 day are not "advisable" strategies unless that person it trying to reach the top al all cost. and in that case you should not own a level 1 polar bear.
