Hi, diluting absolutes is a fine plan; i always dilute my absolutes, to 10%-25%. My aroma chems often diluted to 1%-10%. My experiments consists somewhere around 100 drops of oils, absolutes and aroma chemicals; and that dilutions seems rather workable. Check my site for some indications in the third column of a formulation, to give you an idea (sample formulation).
The reason i dilute absolutes not any lower, is that i often experiment with (cheaper) essential oils, and only replace them by the absolute if i like the composition.
In general, absolutes are rather strong, though not equally and it greatly depends on the rest of the composition.
Diluting to 10% instead of 25% can do no harm, it will only cost you more time to measure the drops if you make greater batches. But remember it's easier to measure 8 drops at 10% than 3.2 drops at 25% (On the downside: you won't be able to make a perfume stronger than 10% fragrance mixture/compounds, if all your stuff is diluted to 10%!!!).
On the safe side i dilute small amounts of precious materials, not all at once. While working, i make notes, and a next dilution will be adjusted accordingly to my findings, i.e. i make higher % dilutions of weaker scents next time.
