Description Fractional quantum Hall quasiparticles are famous for having fractional electric charge. Recent experiments
report that the quasiparticle’s effective electric charge determined through tunneling current noise measurements
can depend on the system parameters such as temperature or bias voltage. Several works proposed to understand
this as a signature for edge theory properties changing with energy scale. I consider two of such experiments and
show that in one of them the apparent dependence of the electric charge on a system parameter is likely to be an
artefact of experimental data analysis. Conversely, in the second experiment the dependence cannot be explained
in such a way.
