I'm no expert on strength training, but I too am doing "a semi i think kinda sorta westside style routine." Westside doesn't train chins, but like you I want to get better at them so I incorporated them into my routine. I tried to mirror the bench press strength training in creating a strength program for chin-ups.
Now for some comments on your routine.
First of all, you don't want to do the same exact exercises on your max effort and dynamic effort days. You should change them up just slightly. I dont' think this is terribly important, though. You probably also want to add in some supplemental and accessory movements. These should target the weak muscles in your lifts, but if you're like me you'll just pick the most commonly performed ones. Also, WSB says that you should change up your max effort lifts every 1-3 weeks, but I don't think this is too important unless you are REALLY strong (which I am not, so I don't really worry about it).
While WSB does help to improve the deadlift, the program does not include any deadlifting. Instead, it focuses on strengthening the legs and lower back as a part of squat training, which in turn carries over to the deadlift. WSB includes a LOT of work for the lower back. Most of the time they do some sort of good morning as a max effort exercise for the squat. Unfortunately, I don't know how to perform them correctly so I stick to lifts that I am comfortable with.
I would say that doing the entiere program in 2 days a week is not such a good idea. You may be able to do all of your dynamic work in one day, but it would probably be better to split it up and add in some supplemental and accessory movements. More importantly, it would be unwise to try and do four max effort movements in one workout. WSB only does one max effort exercise per max effort workout. The reason for this is that max strength is dependent upon neural factors. It is necessary to induce neural fatigue in order to get stronger, but if you try to do four max effort movements in one workout, your CNS will be exhausted and you will not be able to truly max on your 3rd and 4th max effort movements. I assume that 2 max effort workouts would be OK in the same workout, so long as they don't target the same muscles. For example, I do my max effort chin-up and bench press exercises on the same day.
Another comment about your max effort movements: you want to do more than 4 sets and less than 4 reps. WSB says that you should work up to your 1 or 3 rep max. Start at a really light weight and do 3-5 reps, then increase the weight until you can no longer get 3 reps. At this point, go for 1 rep until you max out.
The rest time between sets when doing your max effort exercise should be 2-5 minutes. Just so it doesn't take forever, I only rest about a minute between sets while the weight is pretty easy. I think the point is that fatigue should not limit the weight you can lift.
The rest time between sets when doing your dynamic effort exercise should be 1 minute. This is supposed to be important. No more, no less.
I definitely think you should add in some supplemental and accessory movements, but if you can't for some reason (like time constraints) then you could probably do alright without them. I think they would help your progress, though.
In case you want to use it as a reference, here is my routine. This is the first strength program I have designed. It's not perfect, but it's the best I could do. Ideally, I would workout 4 times a week. This is how I split it up:
Max Effort Squat
Max Effort Bench Press/Pull-Ups
Dynamic Effort Squat
Dynamic Effort Bench Press/Pull-Ups
MAX EFFORT
SQUAT
1. Max Effort Exercise (work up to 1-3 rep max)
Box Squat/Front Squat
2. Supplemental Movement
Leg Curls – 3 to 6 sets of 5 to 8 reps
3. Accessory Movements
Abdominal Exercise – 3 to 4 sets of 8 to 12 reps
Lower Back Exercise – 3 to 4 sets of 8 to 12 reps
4. Prehabilitation Movements
Exercises for knee and hip joints
BENCH PRESS
1. Max Effort Exercise (work up to 1-3 rep max)
Incline Press/Military Press
2. Supplemental Movement
Tricep Movement – 6 to 8 sets of 8 to 12 reps
3. Accessory Movements
Shoulders: Shoulder Raises – (Light)
PULL
1. Max Effort Exercise (work up to 1-3 rep max)
Pull-Ups/Barbell Rows
2. Supplemental Movement
Curls – 6 to 8 sets of 8 to 12 reps
3. Accessory Movements
Lats: Rows / Pull-Ups – 4 sets of 5 to 8
MAX EFFORT PARAMETERS
Load (Intensity) = 90% to 100%
Number of Exercises = 1
Reps = 1-3
Rest Interval = 2-5 minutes
Frequency/Week = 1 (Squat Day) / 1 (Bench Day)
Weeks per Exercise = 1-3
DYNAMIC EFFORT
* Rest is always 1 minute
** Workouts should include 1 set at 80% or higher
SQUAT
1. Dynamic Effort Exercise (8 sets of 2 reps)
Box Squat/Front Squat - 50% 1 RM, 53%, 56%, 60%
(The 1 RM % increases slightly each week. After 4 weeks, I guess you would just repeat the cycle.)
2. Supplemental Movement
Leg Curls – 4 to 6 sets of 5 to 8 reps
3. Accessory Movements
Abdominal Exercise - 3 to 5 sets of 6 to 12 reps
Lower Back Exercise – 3 to 4 sets of 8 reps
4. Prehabilitation Movements
Exercises for knee and hip joints
BENCH PRESS
1. Dynamic Effort Exercise (8 sets of 3 reps)
Bench Press/Military Press - 50% 1 RM
2. Supplemental Movement
Tricep Movement (high intensity) – 2 to 4 sets for 2 to 8 reps
3. Accessory Movements
Shoulders: Shoulder Raises – (Light)
PULL
1. Dynamic Effort Exercise (8 sets of 3 reps)
Barbell Rows - 50% 1 RM
2. Supplemental Movement
Curls (high intensity) – 2 to 4 sets for 2 to 8 reps
3. Accessory Movements
Lats: Pull-Ups – 4 sets of 5 to 8
And just so you know I didn't make all of this up, here are the websites where I got most of the information for this program from.
