this is the prevailing wisdom of TLS and in my opinion it's wrong and you shouldn't do this.
The test is markedly different today than it was in the oldest iterations and even in the 40s and 50s. Only by seeing the test in its most recent form early on can you get the most out of the older PTs.
Mix up your PTs from 40+ and take a couple of the most recent tests early on. Otherwise, you have no benchmark with which to compare the older questions to.
The older PTs are definitely worthwhile, but not in the absence of contrast to the newest tests.
The reasons you mention about not fretting about certain questions is one of the primary reasons to avoid focusing on the earlier tests first. Once you expose yourself to the newest tests, you can better understand the context for some of the oldest questions and realize that they are less similar to what you will see. There are some game types and game styles that have fallen completely out of favor on the newest tests (games where you must see some crucial deductions that either allow you to murder the game or drown in it). There are also some LR that are a little quirkier in the oldest tests, and by and large the LR is more difficult today but also more straightforward (in other words, it tends to favor higher preparation than does some of the older LR). Some of the older LR rely a bit more on very technical matters that make the questions difficult, rather than the underlying logic itself (which is what the newest LR does).
Don't misunderstand--all of the PTs are extremely valuable for prep. But you should
not take them in ascending order or you will be left in the dark until the last few weeks of your prep as to what the new tests actually look like. Mix them up in your prep and eat a few of the most recent tests very early on so you can really break them down and appreciate the test as it is today (and you can repeat them later).
Too many people have this idea that they must save all the most recent tests for immediately before test day. You don't need every PT to be a litmus test for your progress, but instead they should be learning devices to elucidate your personal weaknesses. The most recent tests are the best for doing that. These same people will mercilessly drill and repeat the oldest material and then cram the newest stuff in only during the last week or two of months of preparation. Don't be like this. Instead, PT with the newest material while supplementing it with drilling older material.
If you want an overly generalized "feeling" of the PTs, maybe they look something like this:
<12 - quirky and out of the box LG, technically worded LR that relies more on content than logic for difficulty, moderate RC passages with easier questions
<40 - volatile and challenging LG that hinges on rules deductions, LR more stabilized but still often enough relies on content rather than underlying logic for difficulty, moderate RC and questions
41-50 - very easy LG, moderately challenging LR, moderate RC with slightly more challenging questions
51-60 - easy-moderate LG much more standardized, tighter and moderate LR, challenging RC passages with moderate questions
61+ - moderate and very standardized LG disguised as out-of-the-box games, difficult but straightforward LR, moderate RC passages and difficult, but straightforward questions
This is solely my own opinion but should give you an idea... mixing tests up will give you a much better perspective on what one test is like relative to the other.
