Sure seems like you are.
I went to check. My shortest full adventure of the current campaign was "Plague of Lies". Notes for it are 24000 words (as measured by Microsoft Word). But my longest was the opening adventure of the campaign "The Dogfish" which has notes at over 90000 words.
But I did say a typical adventure.
"Wings of Terror" the current adventure has 42672 currently, but I need to write a few thousand words this week because the hunters elected to stay around for the planet wide celebrations of the transfer of power after they finished the job, and that going to get them facing the dark sorcerer Hergen Gia and the remnants of the terrorist organization they dismantled. Which means I need narration of the ceremonies, notes for the VIPs, and I should probably study up on the force power rules. Also there is still a chance that they'll slip up and run into the bounty hunters that are trying to collect on the bounty Narmo the Beefcake put on their heads.
I also have 18000 words in the document "Short Adventures on Chulzund" that contains two mini-adventures "The Decker Job" and "Thou Shalt Not Escape Calumny", but those were intended really for a single session each (though they took two, my players are overly cautious sometimes). And there is 5000 more words for "Adventures on Breska" for the time the players went to a pirate world seeking black market weaponry. That was a single session though.
So yes, the current campaign is probably in the 350,000 to 400,000 words length at this point once you add up the adventures and all the notes for brainstorming and house rules. I really ought to turn this into a job at some point.
And if you don't buy it, then oh well. There are plenty of people on the board who have asked me for help with content that can attest to how much joy I take in being creative and writing things down.
