Some studies that NASA did researching decompression when going into space showed that if you increase pressure first before dropping it, bubbles were less likely to form. The theory is that a number of the bubble nuclei get crushed during the inital pressure increase and thus the number of bubble nuclei present during decompression is reduced, reducing the likelihood of bubble formation.

Have i read this bit right?

Is it suggesting that it may be benificial to include a pressure spike into a profile?

ie 1) dive at 25m then drop to 30m towards the end before beginning your ascent, or
2) dive 30m then an ascent to, for the sake of discussion, 12m then drop back to 18m, followed by your ascent?
