My initial post which you quoted was "Best glide rate wasn't high on the performance needs list" only meant that a specific glide ratio wasn't a target goal in the development of fighters. The performance goals were Speed, Climb Rate, Altitude and Range.
The Spitfire Mk. I had a much lighter wing loading (and better glide ratio) than the later developed Spitfire Mk.'s. While the later Mk.'s "Power On" performance numbers kept increasing, their glide ratios decreased.
Edit - as for the other posts referencing "glide ratios", there is a distinct difference between a fully functional aircraft with its engine at idle (still making power) and an inoperable engine. An inoperable engine with the prop still turning is a huge air brake, the glide ratio will suffer greatly.
