does tailheavy mean the target CG is closer to the tail?

That is the correct answer although 'actual CG' may be a better term. 25% is always closer to the nose than than 30% which leads me to beleve your calculations of where the 25 and 30% points really are is confused somehow.

Here is another way to look at it: Actual CG is the point that when supported at that point thye airplane sets perfectly level, This point may not be at the point that is indicated in plans or manuals for that airplane This is the target CG. To move the actual CG to the Target CG we may need to move something in the airplane like a heavy battery or add lead to the nose or tail to get the airplane to balance level when supported at that target CG .
