Obviously worth noting that though the NRA/NSRA Construction Handbook is largely cribbed from JSP403, there are nuances and the military guides should only be taken as a guide for civilian ranges, not the definitive last word (but they're free and a decent starting point!).

The ISSF rules are a better guide for usable target points for prone, of min 1.25 mt, the matt under ISSF is 80 mm, so the 1.25 allows the matt to be angled one way for right handers, and the other for the cursed lefties.

We've all shot on squeezed up prone ranges, not good at all, most good prone shooters use every bit of the 1.25 mt's, (and some more!), you could possibly squeeze 5 points in, but not a good idea, it will be a much better and nicer to shoot on range with 4 points.

Sorry, but it's significantly more nuanced than "no".

Our range was recently recertified and the prone points are a smidge less than 1metre. They also converge - the target end of the range is only about 3.5m wide!

1.25m is the ISSF standard and the "ideal", but most ranges make do with less. The military want a metre, and it sounds like they will just about squeeze into that with 5.2m for a 5-lane range.

Moreover, I've never come across a range with the "required" raised firing point outside of cadet/military ranges. What applies to the military is not always taken as gospel for civvie ranges.

0355. Firing Points. When firing is conducted from the prone position on just one firing point a raised platform approximately 450 mm high should be provided. This reduces the possibility of ricochet from low shots hitting the range floor. It may be built into the range floor or be a free standing structure. It should be about 2.5 m from front to rear with a fall of 1:12 from the front
edge.
