Nbajammer, I'm looking at the official TV-Asahi site. For Mach/DeadHeat Mach, they refer it those form(s), including DeadHeat Mach as just Mach (Mahha) in the documentation/explanation for certain parts of the Rider (1-12). For Chaser Mach, they actually keep writing it out as Chaser Mach rather than calling it Mach as they did for Mach/DeadHeat Mach. That's very strange and it could be intentional.

On Note #16 of Chaser Mach after using numerous translation tools, grabbing out my own Japanese dictionary, and asking my former Japanese teacher, the translation is:

仮面ライダーチェイサーマッハへの変身時に使用するベルト. 仮面ライダーチェイサーを開発する際に追加された拡張機能により、スロットに入力された戦闘データとベルト内部に保存された戦闘データを組み合わせ、新たなライダーを試作することができる.

Using Rider Chaser in the belt, Kamen Rider Chaser's enhancements have been added onto through the slot in the belt, adding battle data and the belt's internally stored battle data to create a new temporary rider.

I think the human understanding would be that it augments Signal Chaser onto the current form (Signal Mach) to temporarily create a new form (which is exactly what it did).

Take that as you will, I think it's a new form, but TV-Asahi intentionally differentiated Mach/DeadHeat Mach by calling it "Mahha" and calls Chaser Mach as Chaser Mach, so that might mean something else that we aren't seeing.
