The size difference for your Number Builder TAPs is normal. The reason for this is explained by the differences between the two TAP formats:
The fullwave/wholewave TAP format is the original format, and was originally designed for C64 emulators. Each byte in the file represents the duration of a complete low-high wave, which is how the C64 responds to tape pulses.
However, because the fullwave TAP format is designed to assume a low-high wave, it will not work for turbos which use inverted (high-low) waves. That's where the halfwave TAP format comes in. Each byte in a halfwave TAP file represents the duration of each half of each wave cycle independently.
Basically, the halfwave TAP format is simply a more precise method of dumping tapes. Any tape that can be dumped as a fullwave TAP can also be dumped as a halfwave TAP, and there are some tapes that can only be dumped as a halfwave TAP.
I'll have a look into a waveform checker.
