Concerning the damage done by the teppo, some scholars (such as Motohiko IZAWA) have suggested that 'although the sandan-uchi tactics was not carried out, the horses of the Takeda cavalry were upset when 1,000 teppo were fired at the same time and brought it into great confusion.'
鉄砲による損害に関しては「三段撃ちこそ無かったものの、1000丁という大量の鉄砲の一斉掃射による轟音によって武田の馬が冷静さを失い、騎馬隊を大混乱に陥れたのではないか」とする説がある（井沢元彦ほか）。
