Yes those are her easy runs. Not sure what point you are trying to make by sharing your times
I wanted to see how far away I was in relation to her, and if they were proportional to hers in terms of ability. i.e. as I get faster, will my EZ runs get to that level, even if I don't obviously run 2:27 or so. Even if I get to 2:55-3:05 at some point, what would the equivalent EZ paces would be at that point, etc.
It doesn't work that way.
Elite runners are running a marathon at around 85% of their VO2max. Very good recreational runners are at 75%, and average runners are more like 60%. One of the consequences of having a marathon race pace that's so fast relative to your 3k pace (i.e., vVO2max) is that it's also very fast relative to truly easy paces. A three hour marathoner will frequently hit MP during "non-workout" runs because it's a pace that is usually pretty comfortable when you're feeling good. A 2:28 marathoner is never hitting 5:40 pace just by accident. That's a fast, workout-level pace.
The cool thing about marathon training is that, while your VO2max is largely a fixed value that doesn't respond to training, you actually can improve your fractional utilization of VO2max year after year, until you hit a ceiling that's typically in the low 80s (it depends also on how fast you are, because you can high a higher percentage if you're only running for 2 hours vs. 2:30). As your fractional utilization increases, though, your easy pace stays pretty similar. To the extent that it improves, it's usually due to improved running economy or weight loss (the latter being the only reliable way to improve VO2max in trained athletes).
