Controlloing a camera with markers

//Abbreviation for last layer
m = thisComp.layer(thisComp.numLayers).marker;

//Variables for time
t0 = m.key("0").time;
t1 = m.key("1").time;
t2 = m.key("2").time;
t3 = m.key("3").time;

//Positions
p0=[360,288,-833] //Initial position
p1=[75,288,-641] //First position
p1_2=[75,288,-501] // First subposition, to mantain camera on move
p2=[340,400,-641]
p2_2=[360,308,-550]
p3=[653,288,-641]
p3_2=[653,288,-500]

//Conditionals
if (time <= t0)
{linear (time , 0 , t0 , p0 , p1 )  } 
else 
{
if ((time >t0) && (time <= t1-0.2))
{ linear (time , t0 , t1-0.2 , p1 , p1_2 )  } 
else {
if ((time >t1-0.2) && (time <= t1+0.2))
{ linear (time , t1-0.2 , t1+0.2 , p1_2 , p2 )  }
else {
if ((time >t1+0.2) && (time <= t2-0.2))
{ linear (time , t1+0.2 , t2-0.2 , p2 , p2_2 )  }
else {
if ((time >t2-0.2) && (time <= t2+0.2))
{ linear (time , t2-0.2 , t2+0.2 , p2_2 , p3 )  }
else {
{ linear (time , t2+0.2 , t3, p3 , p3_2 )  }
}
}
} 
}
}

Hi, I have four markers in my last layer that set time for camera´s position. I made it with conditionals but I want to know if there is a smarter solution.
