These are all helpful nmeumonics.
But, especially in the case of Discount versus Premium, it may be more useful to just think of these problems logically.
Think of the journal entry and solve for x.
As an issuer, you are setting up an expense (Debit). This is CARRYING amount, not the face amount, times “MEY” rate. You will always pay the same amount of cash (credit). THIS is the face amount times the stated rate. Balance the journal entry by a debit (premium BC there is less interest) or a credit (discount because there is more interest). Solve for the plug, or X.
Apply the same logic for issuer POV premium and for both discount and premium for investor POV.
For a capital lease (lessee POV), what are you doing at inception? You're establishing the total lease liability. That's why you're only using annuities at this stage. As you know, we must record liabilities at their present value. Thus Dr Leased Asset & Cr Lease Obligation (PV lease pmnts (PVOA or PVAD depending on if made at end or beginning of period) + PV$1 x bargain purchase option)
As time goes by, you reduce the liability owed whenever you make a lease payment. Timing is everything, thus PVAD or PVOA above. I find it helpful to write out a separate Journal Entry for lease payment made (Dr Lease Obligation (plug) Dr Lease Exp (tax or executory cost included w pmnt) Cr Cash (you're decr cash to make a pmnt)) AND Then for the interest expense (Dr Int Exp (CV lease liab x “Lesser” of rates–implicit or lease rate) Cr Interest Payable).

So, I dunno about anyone else. But I only have so much ability to remember so much. I find that I retain rules much easier if I can visualize the journal entries. Then apply what I need to after I see it written out.
For instance, you can see WHY discount yields more interest. Int Expense will be a larger number to balance the entry.
Also, when you have to calculate the issuance of a bond BETWEEN Interest dates, I would never remember what to do (add or subtract which numbers) with tricks alone (no offense). BUT, if I remember that you are getting cash I start to remember the other part of the calculation. So I debit cash (that becomes X). I still setup a bond payable (credit the face amount). Here is where it gets tricky. I know I need another credit to balance it. The rule is that we have to pay back the sort of loan on the bond interest because we need to catch-up to the previous int date. Thus we have a bond payable credit of face amnt x stated int x mm/12). Add the credits to give you the cash on issuance.
