please explain me, why the “code1” creates a smoother transition of alpha and “code2” doesn`t.

code1

```auto

 onClipEvent (load) {
    brems = 4;
    soa = 40;
}
onClipEvent (enterFrame) {
    y = soa-_alpha;
    setProperty(this, _alpha, _alpha+y/brems);
}

```

code2

```auto

onClipEvent (load) {
    ion = 100;
    maria = 1;
}
onClipEvent (enterFrame) {
    setProperty(this, _alpha, ion/maria);
}

```

Both codes are putted on 2 separately mc`s, that contains each ones button The first button changes the soa`s value from code1  
The second button changes the value of maria from code2.

Thank you
