What do you mean? If you want another example try catching whismur with a pokeball, it will pop out(while before 25/12/18 it wasn't). Whismur has 190 catch rate and pokeball 1x bonus catch. Math: 190X1=190/255 = 0.75 (75%).
Just saying though, don't wanna argue. The devs may keep this from us or whatever.
Have fun ^^
