Of course experience and synchronization would matter.
But if the hypothesis is that three people carried a 85 kg, 3.50 m long log, the experiment with two people carrying a 60 kg, 2.50 m is not representative of that.
It is not like they couldn't find a third volunteer and attempt replicating exactly the hypothesis.

Look for "Continuous Beam – Two Equal Spans – Uniformly Distributed Load" here: https://www.linsgroup.com/MECHANICAL_DESIGN/Beam/beam_formula.htm https://www.linsgroup.com/MECHANICAL_DESIGN/Beam/beam_formul... Hint: you'd better put the strongest guy in the middle.
