Resumo todo lo que viene a continuación (extraído de Nxtchat en Slack), Riker cree que las órdenes de compra programadas que tienen más posibilidades (ojo, posibilidades, no certeza) de entrar en el siguiente lote de la ICO son las que contienen una fee de 4NXT.
¿Motivo? Cada minuto se genera un bloque en Nxt, y en cada bloque caben 255 transacciones, y uno de los criterios que se siguen para ordenar las transacciones a confirmar es la fee incluída. Jelurida emitirá la orden de venta con una fee 5NXT. Si hubiese muchas órdenes de compra en ese mismo bloque con un mayor fee, entonces la orden de venta de Jelurida (con tan solo 5NXT de fee) quedaría sin confirmar y seria pospuesta hasta el siguiente bloque, junto con aquellas transacciones con menor fee que tampoco hubiesen entrado en el bloque anterior. Las órdenes de compra con un mayor fee si habrían entrado en el anterior bloque, pero no podrían comprar porque todavía no se confirmó en la blockchain la orden de venta, perdiendo su turno (y su fee)
En este artículo se lee:
“The Jelurida sell offer will be submitted with a fee of 5 NXT. If more transactions than what can fit in a single block are submitted with higher fee, the Jelurida transaction will be postponed to the next block, and none of these high fee transactions will match it.”

if Jelurida offer will go to the next block, will scheduled transactions be executed or they will be canceled?
riker [12:13 PM]
Scheduled transaction are broadcast as unconfirmed transactions therefore anything that applies to unconfirmed transaction applied to scheduled transactions. Once broadcast the scheduled transaction will be ordered according to the standard ordering so surely not cancelled.

But if my scheduled transaction will be included in block A and sales offer will be included in block A+1. What will happen then?

You will miss out your order will be executed but there will be no matching sell offers

It’s a game theory problem, if everyone submits their transactions with 4 NXT fee, and a single guy with 6 NXT, this guy still has an advantage. his transaction, the offer, and as many as can fit from the rest will fit in the block.
But if everyone thinks this way and submits theirs with a fee of 6 NXT, all will lose since the their transactions will be included in a block before the sell offer.
The problem with the 1000 NXT tx fee we used before is that theoretically a whale could submit his buy transaction and 253 meaningless transaction with fee of 999 NXT for example and prevent anyone else from buying.
With lower fee, anyone can afford to spend 5 NXT to compete this way.
This strategy was suggested by @forkedchain who will receive 5K Ignis as bug bounty.

The lower the fee you specify the chance your transactions will be delayed increases but if you set the fee to 5 or more your transaction might be included in a block prior to the Jelurida offer.
I would say your best bet it to place the fee at 4 NXT.
