The WAVA standards do not include a 4 mile table, but one can be added by using the 8k WAVA standard time to predict a 4 mile time, and then interpolating 5K and 8K age correction factors to obtain an appropriate age correction factor for 4 miles. I'd recommend reading further before using this.
I don't have this in here yet. A 5 mile takes a few seconds longer than an 8k (the distance is 45m longer). An appropriate correction is 10 seconds + two seconds for each minute/mile slower than 6:00 pace.
