The funny (and yet tragic) thing is that before too long, the CBP can accuse you of abusing the B1/B2 visa, given your vacation home in FL and frequent travel in/out of the USA.
Also, you are more likely to encounter problems during your next visit because the CBP will become suspicious of a UK citizen travelling on B2 visa. Firebug can comment on this case, including the so-called VWP abuse.
