0% to 100% pollination results in 100% abortion. The tree will flowers again and set fruit at the proper time and harvest will be in jan - feb.
I only wanted to know if this process is normal for all late season fruit trees.
Again it is a bit vague.
It appears you saying every seedling is a new variety, and are never true to type.
There is nothing desirable about a tall avocado tree, it is too difficult to harvest. It did not appear to be very old and certainly is not as impressive as an old mango tree.

Hey Keith, apologies if you're finding the pollination guide a bit confusing, but I am only giving you some solid info on a link of what improves the success of pollination and fruit set. Fruit aborted is typical for unpollinated flowers. Regarding your factors, I can only give you my personal experience. Here in Coastal Southern California, we have fluctuating temperatures, fluctuating water supply, fluctuating humidity, and yet through all of that, in my years of experience with avocadoes, the success is not greatly dependent on weather factors (we rarely have frost). Also, seasons are not always accurate when it comes to regions like yours and mine, since we can have fruit on our trees year-round. There are often times when I will have a few dozen fruit close to ripening in January on trees which have a Summer/Fall season. I believe the flowers on Avocadoes are triggered more on warmth and sunshine, rather than hot and cold (because of this experience).
On the thought of yield, it seems to be most effective and highest yield when there's an opposite (A pollinating a B, vice versa). Because of the hermaphroditic flowers needing to have an opposite (morning male pollen donor crossed to a morning female and vice versa).
You may want to check to see what type your trees are (watch for what sex they are in the AM). Proximity of opposing type is possibly a factor as well. I can say that in my neighborhood, if a neighbor has an opposing type tree, it will help somewhat but not completely in fruit set, and still an opposite is needed within a short distance (preferably within 10-20 feet).
Firming up what I have mentioned again is this article regarding Pollinating and amount of actual fruit which set:

If anything else regarding why your cultivar drops 100% of the fruit at times, it may be simply that particular cultivar, because out of the 8 types I grow, all of them have set fruit in just about every month of the year.
I hope that clears things up for you a little and apologies for any confusion in the previous post.
My best,
Rob
