No method of measuring chamber pressure is 100% accurate.If you measure 100 rounds of exactly the same load, in exactly the same gun, with exactly the same test equipment using the crusher method the measurements will typically vary plus or minus 5% from round to round.Some rounds may be off from the average for that group by 10% or more.
Note that the above calculation of impact force is accurate only if the height h includes the stopping distance, since the process of penetration is further decreasing its gravitational potential energy.The average impact force calculated here is the average over distance, which can be presumed to be proportional to, but not the same as, the average over time.
