I assume so - it may have changed, but CI used to be based on company assessed costs and I believe the FMC 'reacted' to the CI in a chosen way - it is after all just a number and depending on what factors the FMC has to run the index, speeds for a given number could vary. It may well be that nowadays the Boeing FMC has just one fixed scale - I don't know, but the other factor which renders the information abenk requests of little value is that any particular company will have different reasons for choosing a particular speed profile - eg maintenance v fuel weighting/wages etc, so unless abenks company has the same 'running costs' it is of little interest for Company A what Company B does. I guess all airlines now operate to a lower CI than they did.
As 737ng said, in a well-run airline CI should reflect the sectors involved and be provided to crews for that sector, but some companies just have a fixed CI which is a fairly blunt instrument.
