I think fit gun is additive and imporvement with k = 1, but improvement seems a little bit more complicated, from akashi's improvement page :

Accuracy multiplier for various equipment like guns, AP shells, torpedoes, and AA Radar is currently believed to be 1.[12] [13]
 * Effects on low morale seem to be lower (that is, the morale modifier is applied).
 * Overall accuracy bonus might have an upper limit of 10%, or a limit that depends on type or number of equipment.[citation needed]
 * Preliminary tests suggest that night battle accuracy is unchanged.[14]
 * Radar improvements should give accuracy bonus.[15]
