cl_crosshairusealpha vs cl_crosshairalpha confusion

[andrewwan1980]

I am very confused by the use of cl_crosshairusealpha. Is this an integer/number (1,2,3,4) or a boolean/true/false?

In http: strategy.counter-strike.com getmoreheadshot.php it says cl_crosshairusealpha 6 to brighten up crosshair. Maybe this is a typo and it was meant to be cl_crosshairalpha 999, cl_crosshairusealpha 1. Please can someone confirm.

Whoever wrote that article above should update/correct it. cl_crosshairusealpha default=0 not 1 as it states. Default cl_crosshairalpha=200.
