Henning have already explained it in this thread that the Silvermax spectral sensitivity is identical to Agfa APX 100

Same way as Scala 200X emulsion is based on the APX 100 emulsion. So, Adox Silvermax, Agfa Scala 200X and Agfa APX 100 share absolutely identical spectral sensitivity. Adox Silvermax sports modified APX 100 emulsion, so does Agfa Scala 200X, so what? The fact that those 3 films share identical spectral sensitivity does not mean they performs the same.
