Are you talking about your daily pace when you're in base phase?
Do you even do a summer base? Or do you train for track during the summer?
Do you consider yourself a mid-distance guy who does XC or are you a equally interested in XC and track?
I think most people would need more info to know if your paces are appropriate.
With developing runners, it is OK for the daily runs to be a little closer to a focused pace than just a jog. This is because most new runners are aerobically deficient and will gain a lot from becoming better in this regard. That and the training of a focused daily run really isn't too stressful. I like for mine to do this during the base phase in summer and winter when there aren't any workouts.
Someone in a previous post suggested the same. As you get closer to hard training and key meets, the daily runs become more recovery in nature and then pace isn't a big deal - whatever is needed to still get the mileage in while leaving you ready to successfully complete the next workout.
Just looking at PRs, I would say you look like you have really good tolerance for high lactate/H+ situations. 50.x and 1:53 indicate no real drop off from 400 to 800. A 1:53 800 runner who is a miler should probably be able to pop somewhere between 4:06 and 4:16 for a 1600, though.
I would say you have some aerobic development to do and I would be interested in seeing where your tempo work is in the season and if you remove it completely at some point...perhaps too early? Or if the tempo density is too low in the training plan. Sometimes 800 runners avoid it because they're just better at workouts that involve tolerating high H+ conditions.
I also agree with the person who said you would probably benefit from some of Tinman's 90% CV workouts. Or perhaps look into Daniels-style cruise intervals for your tempo work instead of straight tempo running.
Tempo goal (and this is a ballpark figure) should be about 60s slower than mile date pace. It also would hurt to do some occasional early season work at 1/2m pace. So add between 80-90s over mile date pace. This will prep you to handle better cruise intervals or short tempo runs that are closer to 10k pace.
I'll let others chime in. There are a lot of ways to attack it. I don't see any deficiency in 400/800, so my guess is you've got that portion figure out and could now benefit from improving the clearance of H+ instead of just tolerance of it.
