I *think* what you're saying is "I'm doing the exercises with less and less assist" (at this point, no assist) but my times have gone up.
Yeah, yer times have gone up, but so has your workload, by heaps!
You're doing great, girl. Now that you've got an "unassisted" benchmark, do it again the same way next time and you'll see your time drop.
BTW, if I haven't told you lately, I really love your icon. My inner dawg is lying in the sun today...
