Electoral volatility caused by vote switching between parties falling below 1% of the national share in both the elections at time t and t+1. It is important to clarify that this category is not computed by aggregating the scores of each party falling below 1% and then comparing the overall sum at time t and t+1. Conversely, each party's volatility is counted separately - up to a specification of 0.1% - and then added to the calculation of dev_othv. This choice has been made to avoid underestimation of Total Volatility but at the same time to maintain a distinction between parties above 1% and parties below 1% for the calculation of the two components of dev_regv and dev_altv.
