For Time Spiral Remastered, as noted in our original article: https://go.mvpsportsandgames.com/news/PDWF4J8DG , the opening allocations were relatively small; accounts were allocated according to the ARA allocations system:  https://go.mvpsportsandgames.com/news/YX1BJANVI

The allocation algorithm included all direct MVP mtg orders but gave more weight to Draft and Set booster preorders from Zendikar Rising and Kaldheim sets. If your account qualified for any units you will have up to 96 hours to purchase them; no need to rush. i.e. it is impossible for any other accounts to 'get' your units while they are on ARA reservation hold.

Unfortunately overall there was not enough quantity to get full units to even half the qualifying direct accounts, we're hoping for more units to be announced by the manufacturer but as per the below at this point it seems unlikely. On a positive note, there was however a fair amount of movement amidst the ARA rankings lately with many accounts moving up into qualifying tiers.

More detailed market info:
It appears the manufacturer Wizards Of The Coast intended for Time Spiral Remastered to be limited one-time print, with most of the units coming on release/wave1, and very few coming in a wave2 or 3, and no plans to reprint.

That statement could be seen as attempting to create just more fomo etc however our recent posts regarding opening allocations have generally proven to be accurate regardless of nomenclature. Case in point regarding ZNR & Kaldheim Collector boosters dramatically coming down in price vs Commander Legends dramatically increasing, whilst both Mystery Booster and Jumpstart have largely performed post-release according to the initial market info we posted pre-release. And so on.

Did Wizards get the TSR print run right? Well, that is the Amazon question, i.e. how many did Wizards want to sell direct to the public through their Amazon storefront?  A fair amount it would seem, but perhaps not enough. See our initial article for review, and so far we have not seen anything in the market that would confirm otherwise. Baring the miraculous, it's hard to see markets sustaining under $170 anymore regardless of content at this point.
