Netlogo: Creating starting conditions for myvar-last-tick

I'm trying to create a variable in Netlogo that changes based on its value last tick. I've followed this question thread in how to create such a variable, but I'm having a bit of trouble creating the initial conditions, because at tick=0, there is no myvar-last-tick because there was no last tick, so Netlogo autosets myvar-last-tick to 0. How can I create myvar and myvar-last-tick such that when tick=0, myvar-last-tick is the same as myvar only at tick 0? To be clear I would like to program the variables such that they follow a pattern like this, although for my actual program the rate of decline would not be constant like in this example.

Before you call your go procedure (i.e., your schedule), you should call a setup procedure. Usually, the very first thing your setup procedure should do is all of your global-variable initializations (perhaps by calling a setup-globals procedure). You can initialize myvar-last-tick and myvar to anything you like. Just make sure the the result of your first call to go will produce the starting outcome you want.
