My experience in WI, MD, and NY is that the Lorette method does not work reliably. I either got dead stubs or vigorous regrowth, rarely spurs. Horizontal training does work. Lorette pruning was developed in northern Europe, which has, or had, a much more equable and consistent temperatures and rainfall than most of continental U.S. as well as quite different photoperiod. (New York City, for instance, is about the same latitude as Madrid.
All this depends, to a large extent, on the tree. Dwarf rootstocks increase the likelihood of spurs developing with any treatment, as do certain varieties. Asian pears are especially prone to making fruit spurs. Put a precocious variety on one of those dwarfing rootstocks and the plants can't help but make spurs.

I have been able to produce fruiting spurs on my laterals by this method, but it is just my observation that the technique may be preferred, I have no real 'control' trees with horizontal training alone, so do not know relative success rates.

It consists of cutting current season's shoots back to three to five mature leaves after they have grown about a foot, and about the diameter of a pencil, and have started to become woody at the base. Flowering spurs often develop at pruning cut sites as a result of weakening the vegetative growth, but flowering is also increased throughout the tree because of better light penetration./

This ensures regrowth will come from the less well developed buds near the shoot base. Growth from these buds is weaker and more readily transformed into fruiting wood. The Lorette method is preferable to leaving longer stubs, which not only produce more regrowth, but are usually stiffened in an upright position as a result of the pruning/."
