Three things:
1. If you're fairly new to running, you can probably repeat the same plan with minor adjustments and continue to improve.
2. But if you've been at it a few years, and the Hanson's advanced plan (with peak mileage at 50 mpw and dual build-ups of long 10K-pace intervals and a sustained HMP run) got you to 1:30, you should probably assume that you'll need to progress the plan to run faster, at least in terms of overall mileage and volume. Some progressions go from week to week (like the HMP run goes from 3 to 7 miles over 18 weeks), while other progressions go from season to season (like peak mileage and overall workout volume).
It's not so much the time you ran in a race, it's how many seasons or race buildups you've been through.
3. Something else to think about is if you can complete the workouts at the currently prescribed paces. As you get faster, those workouts might actually get harder. A 7-mile HMP run sounds impossible to me (and I've run 1:20 a couple times). 2 x 3 miles at 10K pace sounds like a pure fantasy workout to me. But other people say they don't have a problem with those kinds of workouts. If you were a 1:25 HM runner, do you think you could run 6:29 for 7 miles? 6:11 for three miles, twice? That's the kind of question I'd ask myself, and re-evaluate the answers as my fitness came around.
