Acutally a 45 minute SI for Nitrox divers is pretty typical in all of Florida: at least the east coast and Keys. I just dove in Jupiter this morning and got a 45 minute SI between the dives (both dives lasted 52 minutes including the ascent and safety stop and I hit 90 feet on dive 1 and 85 on dive 2). I stayed 5 minutes outside of deco per my main computer and 10 minutes outside of deco on my back-up computer on the second dive. I also recall that I got a 45 minute SI when I made a double dip on the Eagle with Conch Republic earlier in the year and the same SI on a double dip of the Spiegle Grove with Silent World in May. On a dive such as the Spiegle Grove or Eagle or reefs in Jupiter, one needs to keep the dives somewhat shallow (around 90 feet on dive 1 and shallower on dive 2) if one wants any reasonable bottom time before hitting deco on the second dive, but a double dip is doable with a 45 minute SI.
With EAN36 this is perfectly normal. I've done these dives many times. With JDC, these dives are time limited rather than gas or deco limited. All my dives are 52-53 minutes as bottom time is limited to 45 minutes.
