Why is it that you still do not understand the whole premise of MLH theory? In this case, it's running at about "half frame rate", which fully explains why it would be oscillating at double the pendulum period.
Prove this statement to be true.
The fact that I have to prove this you at this point, indicates that for as long as you've been debating MLH as "ridiculous" you haven't yet digested this one VERY CRUCIAL cornerstone of MLH theory.
If you throw an object or swing a pendulum on earth and film it -- then just replay that film at 40% speed... it will behave EXACTLY per the physics of the moon. It will be non-discernable.
This effect can also be approximated by a combination of factors - such as for the astronauts, you alternatively provide upward lift (via a thin cable) by say 50%, which emulates 1/2 gravity by itself (mostly) -- and then from there, you only need to slow the frame rate to about 60% to approximate Moon gravity (they combine) - -however, if dust rises with the foot, that dust would fall about 70% faster than it should on the moon.
Realistically, just how are going to move 30% faster? How do they estimate it?
Just approximated is fine. They practice a few times, get a little coaching/feedback and then get decent at it. Since there is no "exact measurement for what constitutes natural movement", they merely need to move fast enough that if you sped up the replay to the filmed rate, it would look "unnatural". Not need for precision on the 30%. 25%-40% will all suffice.
Where is the proof of all this?
The only MLH proof required here is "feasibility". In the case of the SEQ pendulum, given that "if this were the moon, it would be 13% too fast"... this indicates "things aren't right -- someone is modifying the playback speed". So -- THIS discrepancy is "evidence", indicating frame rate adjustments were made.
The foundation of MLH theory resides on two things:
1. Showing things that were IMPOSSIBLE (indicating a mess-up on their simulation), or "a series of things that are very Un-likely"
combined with
2. Showing that faking these things was Feasible.
My main focus on these Theses is on #1, but sometimes falls over into #2 (such as with the replay rate changes, and cable suspension)
