The Ilford charts are pretty loose IMO. You're still guestimating times when the X and Y don't intersect on a given time combination. For instance, how long is the required exposure with an indicated 2 second exposure on this chart?

Run some test. You don't need to use much film; strip tests using the dark slide will give you a pretty good starting point. Ektar's pretty forgiving, so your results might not be as varied as you currently think they'll be.
