You are correct. Note that in the params dialog, only "taps" is underlined. This means that decimation can be changed at runtime.
I'm not sure whether there is an easy change that can be made to support what you want. If you feel this is important, please add a feature request as an issue (https://github.com/gnuradio/gnuradio/issues).

I'm using the following diagram to test it, where
the first freq sink (x1) has bandwidth fixed to samp_rate/1 and its rational resampler have decimation fixed to 1
the second freq sink (x2) has bandwidth fixed to samp_rate/2 and its rational resampler have decimation fixed to 2
the third freq sink (x5) has bandwidth fixed to samp_rate/5 and its rational resampler have decimation fixed to 5
the fourth freq sink (variable) has bandwidth fixed to samp_rate/decimation and its rational resampler have decimation fixed to decimation
I run the diagram, decimation default value is 1 and all seems to work
Then I change decimation in the GUI Range and the variable block don't work
Then I stop the diagram, change the default value of the GUI range to 2
I run it again .... it works
Then I change the value of decimation in the GUI range .... and it does not work
The x axis change but the "image" don't ... what am I doing bad?
