It's supposed to be LESHIY.
The "2.0" denominator is from LELYA not LESHIY.
As there are small variances in every individuals' regulator pressure setting (since we cannot read out the EXACT pressure setting unless we have a special tester (and that goes for the Huma one as well, although it has pressure tickmarks on it, it is still ball park) my hammerspring clicks are not the same as yours. So you will need to buy a chrony. Any cheap one will do.
