Manner of reciting and blowing on one's body after reciting the 3 quls

Please clarify the procedure regarding the hadith below.

1. Should one read the surahs once, then blow, then once again and blow, then again and blow. Or should one read 3 times then blow once? Or should one read once and blow 3 times?

2. Should one blow such that a bit of saliva comes on to one's hand when blowing?

It is narrated from Sayyidah ‘Aaishah (radhiyallahu ‘anha) that every night, when Nabi (sallallahu ‘alayhi wa sallam) went to bed, he would cup his hands together and blow over them after reciting Surah al-Ikhlaas, Surah al-Falaq, and Surah al-Naas. He would then rub his hands over whatever parts of his body he was able to, starting with his head, his face, and the front of his body. He would do so three times. (Sahih al-Bukhari, 5017)
