They are the same thing. As the developer becomes depleted you pour out part and replenish it with fresh.

The problem is that this only works right if you have a high volume line running. Therefore all the confusion over the years about using the chemicals "one shot" rather than replenished.

The spreadsheet links I posted are *NOT* for replenished use.

The "starter" is what makes the "brand new" developer appear that it has been used and replenished.
