Don't worry. I am a native speaker and I had and still have as much difficulty interpreting what the OP quoted from Ilford originally as you have with it
Once the full reply was shown it appears that contrast may be of minor concern to Ilford or no concern at all in all cases of developer times except those given for ID11.
Ilford says: "We supply the information on our tables to give speeds using different developers but these are more accurately described as EI values (Exposure Index). The contrast at the particular speeds with particular developers will be variable and not something we have ever quoted."
I still wonder how Ilford works outs the times it does give as EI values Is there a formula for it or what
It does give a time for Ilfotec HC of 8 mins for an EI of 125 which is 1 min less than for HC110 Whether this produces a negative that looks more like the OP's neg at 5 mins I have no idea
Hopefully for those who use Ilford film and Ilford developers other than ID11, the resulting contrast of the negative is close to "normal" or close enough that MG papers can cope with the differences

I have repeated my tests with Ilford HP5 in HC110 at Ilford times and this creates a G-bar value (or curve shape) that is in line with a "normal" development. It could very well be only the FP4 HC110 combination that results in a too steep curve.
