hanbroloLucky_Shoti dont have a set interp ratio...try setting it to 2 in your hitscan classes configs and 1 in your projectile classes configs (ie 2 when cl_interp is 0.303 and 1 when cl_interp is 0.0152). This is assuming your updaterate/cmdrate is 66. This should give you the desired interp. If this doesn't work you're doing something else wrong.
EDIT: also for hitscan the commonly recommended value is 0.0303 not 0.033. the idea is to use 2/66 (interp_ratio divided by updaterate/cmdrate) for hitscan which is 0.0303030 continuing. not sure why so many people use 0.033, seems to be a simple math/rounding error or possibly a typo to me.
Thank you soooo much man
