I can't afford that kinda book and I don't have anyone that can find me a copy for my computer. *shrugs* So I couldn't tell you how well they apply, but I am sure they are good. A lot of people had a hard time understanding spheres, paticuarly that advance/complicated magic requires them to work together and how to work with other mages to combine spheres. x.x
There are plently of spheres that are quite usefull and potent on there own, but some you almost have to combine.
Corespondance only lets you see distant places, stop people from seeing you from distant places, and make you move quicker to distant places on it's own. lol You start adding other spheres in it gets interesting. corespondance, time, entropy work paticuarly well together for seeing possable out comes of things in much grater detail than any of them could on there own.
Time has very few uses beyond giving you exstra turns and seeing the affects of time displacment. There are a few but most of the uses from time come from other spheres like talking about entropy before, and delaying the affects or stretching out the affects of other spheres.
Prime is almost made for feeding other spheres, particularly pattern spheres as it allows you to manifest pattern from prime.
and the groupings and affects of magic work together in other ways that arn't very well explained ether.
Dynamic - Correspondence, Mind, Time
Pattern - Forces, Life, Matter
Primordial - Entropy, Prime, Spirit
each group works with each-other a little better than others, it's not a big affect but it can be brought out in a ritual for a grater affect.
Same with the spheres having various afinites...
Strength - Life
Dexterity - Forces
Stamina - Matter
Charisma - Spirit
Manipulation - Entropy
Appearance - Prime
Perception - Correspondence
Intelligence - Mind
Wits - Time
And
Correspondence - Mercury
Life - Venus
Forces - Mars
Mater - Jupiter
Time - Saturn
Spirit - Uranus
Mind - Neptune
Entropy - Pluto
Prime - ? Sun / Earth / Solar system itself ? (it's earth =p)
The sphers also have a flow for the way the energy goes in nature and following it, using it is a grate boon:
It starts and ends at Prime by the way, another reason I say prime is important... lol
But just for an example there having seen what you are targeting with time/correspondence lowers the difficulty. Perception -> time/correspondence
And even if you don't have mind/spirit Conseption -> Focus -> Form can help some with materializing a patern from prime.
There are also several materials and the like asosiated with each but they tend to be unique to each sphere.... MOST of these are focus' and are tradiltional and there power comes from that.... or are realated to the celestial avatar
