Since the PSA states that the amount is modifiable, she could be awarded a different amount based upon proof of changed circumstances.
There is no "cap" on final divorce support awards.
She is bound by the PSA as to the duration of the support.

Unless the PSA is set aside by the court (for example, if one of the parties objects to the agreement based on fraud, duress, or one of the other limited grounds upon which a PSA may be challenged in VA), then the court MUST follow the contract terms for spousal support as set forth in the PSA (see VA Code Section 20-109, subsection C in particular). Accordingly, the answer to your questions lies in the specific wording of your PSA, taken as a whole. It would be imprudent to attempt to interpret particular sentences in isolation, as there very well may be other provisions elsewhere in your PSA that effect the support provisions that you have recounted here.
So, my suggestion would be to take your PSA to a lawyer for an appropriate professional review and advice. I would certainly encourage you to seriously consider retaining an attorney to represent you at the support hearing.
One additional note: There are no " alimony guidelines" in Virginia. Some counties, like Fairfax, have a formula that they use for setting TEMPORARY (known as pendente lite) support. However, this is limited to support paid to the CURRENT spouse while the case is pending. Upon divorce, whether there is an award of alimony/spousal support to the now former spouse or not, how much, and for how long, is determined in accordance with all of the factors set forth in VA Code Section 20-107.1...(or by agreement of the parties).
