Explain please i want to know how much CPU used my scripts I made 3 cuts

console.log("Start = " + Game.cpu.getUsed());
..
console.log("T = " + Game.cpu.getUsed());
..
console.log("Var = " + Game.cpu.getUsed());

I expect next log

Start = ????
Var = ????
T = ????
.. and repeat
Start = ????
Var = ????
T = ????

But i revived next Logs, why "T" was display without "Start" and "Var" after some cycles

[4:02:53 PM] [shard1]Start = 0.295728
[4:02:53 PM] [shard1]Var = 2.758834
[4:02:53 PM] [shard1]T = 9.199415
[4:02:55 PM] [shard1]wall repair time! walls.length = 0
[4:02:55 PM] [shard1]nothing damaged enough to repair
[4:02:55 PM] [shard1] E = 504/800 Lo = 3/3 HR = 1 UP = 3 BU = 4 DD = 0
[4:02:57 PM] [shard1]Start = 0.19143
[4:02:57 PM] [shard1]Var = 2.036277
[4:02:57 PM] [shard1]T = 7.996323
[4:02:59 PM] [shard1]T = 5.138256999999999
[4:03:01 PM] [shard1]T = 4.808282999999999
[4:03:03 PM] [shard1]T = 5.401028999999999
[4:03:05 PM] [shard1]T = 5.394404
[4:03:07 PM] [shard1]T = 4.252630999999999
