Works fine with CB Conditional. You can even condition based off the progress using Custom > Value and substituting in the progress field (e.g. [cb_progressfield]), which gives a value of 0-100 depending on progress. May not work fine if you're not up to date though.

Ok, so I understood it as you wanted to conditionally show/hide fields based off the completeness of a progress field. You're instead having issues with it asking to complete fields the user doesn't have access to. Please ensure CB, CB Conditional, and CB Progress Field are all up to date as believe I've already fixed this.

Was able to confirm. It's not able to handle conditions that are dynamic. Only static conditions or access checks will cause it to be removed. It needs to check if the profile owner has edit access, but CB Conditional doesn't provide a way to easily do this from PHP since the edit PHP condition checks are only done on save and may need to make improvements to CB Conditional as well.
