We study small field models of inflation which are
able to yield high tensor-to-scalar ratio. These models

additionally conform to known values of CMB observables,

such as the scalar index, it's running and the running of the running.

We will discuss some essential theory, and present the numerical

package we employ, as well as some of the methods.

We will then present the models studied, and discuss

the motivation of studying these models in particular.

Finally we discuss some discrepancies found,

between analytical results and numerical ones,

and track the origin of this disparity.
