Okay, I think I've got Inheritance now, rate is 1.86646^T

Basic strategy: buy Provinces, trash them to Gold, trash Gold to Duchy, Duchy to Worker's Village, Worker's Village to Silver, and Silver to Estate.

Use extra buys to buy Copper, spend Copper to buy Provinces.

Deck is V Provinces, Z Stonemasons, W Estates, R Coppers, where Z=16.6089V, W=20.3227V, R=14.9317V, and a constant number of Scrying Pools.

Draw all cards with V+R=15.9317V Estates

Play V Stonemasons, trashing V Provinces gaining 2V Gold. Draw with 2V Estates.

Play 2V Stonemasons, trashing 2V Gold gaining 4V Duchies. Draw with 4V Estates.

Play 4V Stonemasons, trashing 4V Duchies gaining 8V Worker's Villages. Draw with 1 Scrying Pool.

Play 8V Stonemasons, trashing 8V Worker's Villages gaining 16V Silvers. Draw with 16V Estates.

Play 16V Stonemasons, trashing 16V Silvers to gain 17.6089V Estates and 14.3911 Stonemasons. Draw with 1 Scrying Pool.

Buy 1.86646V Provinces and 27.86942V Coppers, 29.73588 cards total.

k=1.86646 is the multiplier, so total money/VP scales as 1.86646^T

Note that if you do the Stonemasons in the order stated, you run out of actions, Estates, and Stonemasons in the middle. However, all you have to do is run the supply chain in multiple parts: take 0.125V Provinces, trash those to Gold to Duchy to WV to Silver to Estate/Stonemasons, and then do the next set of 0.125V.

Here's the Mathematica code I used:

`NMaximize[k, V+B+C+D+F+Q+3G <= Z+(2C+2F-T) && k*U == U+2D-F && 8*k*V + 5*k*Q <= (3(X+2V-B-G)+2(U+2D-F)+R) && k*V+k*Q+(k-1)*R<=Y+W+2Q+2B-C-D+T && k*X == X+2V-B-G && k*Y == Y+2B-C-D+2Q+4G && k*W == W+T && k*Z == Z + (2C+2F-T) && Y+2B+2Q+4G-C-D+W+T >= V+B+C+D+F+Q+3G&&Y+2B+2Q+4G-C-D+W+T >= X+3V+U+2D+2G+Q+R &&Y+W >= X+V+U+Q+R&&V>=0&&X>=0&&Y>=0&&Z>=0&&C>=0&&B>=0&&T>=0 && Q>=0 &&R>=0&&U>=0&&D>=0&& T<=2C+2F && V==1, {k,V,B,C,Z,W,X,Y,T,U,D,F,Q,R,G}]`

where {X:Gold, Y:WV's,Z:Stonemasons,W:Estates,V:Provinces,U:Silvers,Q:Duchies,R:Coppers} are in deck at start of turn, and {B:Gold to WV,C:WV to 2-cost,D:WV to Silver,F:Silver to 2-cost,G:Gold to Duchy} are trashing with Stonemason. Assumed all Provinces/Duchies get trashed each turn, Province to Gold and Duchy to WV.
