Parity Max Gas Limit dropping

Question

When running my chain my gas limit drops drastically from the set limit of the genesis block "gasLimit": "0x3B9AC9FF" due to large gaps both in time and frequency between the transactions that require the high gas price, I attempted to correct this by reducing the "gasLimitBoundDivisor": "0x0400" to zero, however parity expects a non-zero value, how can I set a high ceiling on my gas limit that wont drop below a certain level without requiring any of my low gas transactions to push up drastically by putting an equally high floor as with minGasLimit.
