REIRYOKU LEVELS:

Basic Spiritual Power: This level of spiritual power corresponds to those possessing a level of spiritual power that is minimal. This level of power is common among those who may or may not be spiritually aware to a small degree but otherwise have no real spiritual power. This is also a common level of power for a regular human.

Average Spiritual Power This level of spiritual power corresponds to those possessing an average level of spiritual power. This level of power is common among those of significant spiritual awareness and may even possess powers of their own but the power levels can vary among individuals. This is also a common level of power for a low ranking seated and non seated members of the Gotei 13 or lesser power individuals.

High Spiritual Power : This level of spiritual power corresponds to those possessing an above average amount of spiritual power, which is finely controlled. This level of spiritual power is common among those of an average lieutenant rank and high ranked seated officers. (Lieutenant-class)

This level of spiritual power is reflected in its ability to enhance a user during combat as well as its ability to affect the surrounding environment on a controlled level, allowing the wielder to use it in combat to startling degrees. (Advanced Captain-Class)

DIFFERENCE BETWEEN REIRYOKU AND REIATSU

Firstly let me make something clear. A common mistake most readers make. REIATSU isn't the energy level.

The difference between spiritual energy and spiritual pressure is simple: Reiryoku(spiritual energy) is the amount of energy a being has stored within their body or soul, whereas Reiatsu(spiritual pressure) is the pressure that a person's Reiryoku exerts. In other words, Reiryoku is potential while Reiatsu is energy in use and can be sensed by other spiritually aware beings. In general, those with high levels of Reiryoku will often have the highest levels of Reiatsu also. A skilled warrior can overcome a person possessing greater Reiryoku by possessing greater Reiatsu - this is achieved by having greater control over their own spiritual energy.

Also the amount if Innate Reiryoku is important but it can be increased with training. All shinigami go through this process. Aside from some cheated bastard like Ichigo who had insane amounts of energy from the beginning and were only unable to properly use it. The bastard was already at Immense level from the start and later reached immeasurable.
