Yes. Your statement t assumes there are more equations in the question bank than presented to a test taker in a test. That assumption is not valid for tests 3/4 and 5/6.
I strongly doubt that each of those tests has only 31 quant and 36 verbal questions and is completely non-adaptive. Without being adaptive, the practice tests wouldn't work.
People with strong skills would see many easy questions and finish the test early and easily score very high, and people not as skilled would be faced with many questions that they'd have no idea how to answer.
The only reason why the GMAT can use only around 30 questions per section and still produce a meaningful score is that it's adaptive. It's for a similar reason that the new digital SAT, which is adaptive, can be so much shorter than the paper-based SAT, which isn't adaptive.
So, without being adaptive, practice tests 3 to 6 would not produce accurate scores.
What can be the case is that each of those tests has only enough questions to produce one set of questions for each skill level. For instance, for a test-taker who is at around 46 in quant, test 3 may be able to provide, basically, one set of questions that fits that test-taker's skill level. If that test-taker retakes and scores close to Q45, the test will provide mostly the same questions.
In any case, it's straightforward to determine how many questions are in the banks for those tests since people have taken the time to find all the questions from tests 3 to 6. So, the counts are available.
ChiranjeevSingh probably knows.
