Hmmmm... It seems like you're using a similar drop count that I'm using but my sensitizer seems to take longer to absorb (assuming you're also using COT 320). Maybe my darkroom is too humid (my hygrometer is perhaps wrong) to prevent enough evaporation of water from the sensitizer during coating. Do you know what Relative Humidity your environment is at? Do you have much excess sensitizer after your coating or is it all absorbed after the minute?

Thanks for your input!
