It's a fact that changing measure systems or knob turn effect causes problems. But you have to do it if shooting or doing shop work.

In the shop use use Thousands of inch on the mill or lathe and have micrometers rules and dial and veinier calipers to suit. Wood work I always use fractions and use appropriate rules calipers etc.  Also have sets of metric mikes calipers rules etc & use them when appropriate. Start the day or job lay the right instruments and don't switch off it's not a problem.

Shooting no different Anschutz with German sights have to twist backwards American receiver sights the other way. Tang veinier sights very different, have been able to minimize tang trouble by using sights that read the same way, Lyman 17's excepted. It's easy to make a mistake but soon as you start shooting it falls into place . Good dodge is a tape marked reminder on the stock. Have not owned or shot Anschutz in years no doubt would need a reminder

Have seen many hand lettered signs "red right returning" in the wheel house on foreign ships . We are the only ones marking channels that way.  Rest of the world green on the right inbound .

Happy new year Jose!
I have to activate my noodle when I adjust windage on my Heilman soule sight. It is on the DST high wall for now. I still haven’t had the perfect conditions to shoot it with my new eye. It seems like nothing but rain or fog since my surgery

Agree with Westerner tang sights are the easiest to read. Larger with more distinct marks. Small changes I need a magnifier to read the graduations, but far less likely to make a mistake than click counting on a modern scope or conventional rear sight.

Only good thing about a click sight is you can make small changes strapped in from position. Rarely needed with single shot rifles. Put a dial indicator on most they have backlash and don't adjust reliably . That's why many experienced shooters always adjust in the same direction.  Too high screwing it down to desired. Or the reverse too low and up to desired, either one used every time not switching methods.

Match director Smallbore silhouette many times I was asked how many clicks to change point of impact one target to the next. Showed them my sight settings in MOA for the targets, CPTR, pasted on the side of my cartridge box. Correct my outfit for THAT range. Looking puzzled "no how many clicks" usual response. Considering equipment variance no answer for that question .
