Fourth Year Still Mixed

Got another fit-test last week, once again a year out.

Weight: 160 lbs. (+1 lbs.)
BMI: 25.8 (+0.1)
(My weight has fluctuated up and down but stayed basically the same.)

Measurements: Less 0.75 inches around shoulders and 0.5 around chest (significant? measurement error?). Up 2.25 around waist, down 2.5 around hips (kind of bizarre). Up 1.25 around thigh, 0.25 around calf. Down 0.5 around upper arm, 0.2 around forearm. These fluctuations are strange.

Fitness Scores
Overall: 51 → 65
(1-100, 50 is average, higher is better, compared to other males my age)

Bodyfat (3-Pinch Measure): 59 → 48 (14.2% → 16.2%)
Bodyfat (Impedance Measure): 40 → 35 (17.4% → 18.4%)
(This seems like an odd result, given my strength gains over the year. Neither of these measures is terribly precise, though...)

Resting Heart Rate: 25 → 83 (76 BPM → 58 BPM)
Active Heart Rate: 29 → 90 (115 BPM → 77 BPM)
(This was the most dramatic improvement.)

60-Second Situps: 75 → 55 (45 reps → 38 reps) (don't think I did my best here)
Maximum Pushups: 67 → 75 (29 reps → 33 reps) (good form, increasing reps)
Sit-Reach Flexion: 68 → 70 (18.75 in. → 19 in.) (still need more flexibility work)

Given how hard I've been working, I wish it wasn't so much trouble keeping strength gains and fat losses. Need to refocus on diet. Good food abounds.
