Correct.........this has been well known for many years. It also improves the effectiveness of the static wicks as well, although in the 145 with its many pointy extemeties, it remains a problem.
I can reduce it somewhat by slowing below about 270, which is something to do in moderate bumps anyway and fast enough to usually keep ATC happy.
Also the freezing level is the best place to generate static and also among the higher risks for taking a lightning strike, so I try to avoid prolonged exposure if possible when operating near areas of convective weather.
