Yeah, I agree partially with you

I myself do not use normally the recognition manual, I just try to estimate the mast or funnel heigths and use the rangefinder tool manually by setting myself the base heigth to be used. I love that SH4 allows to do that and miss it a lot in SH3 and the UBM Add-On
Fact is, after some trial and error I have become quite proficient at it and my ranges & bearings use to match what the Position Keeper shows. Playing this way is much rewarding
